The flexibility of the Artemis module starts with SparkFun's Arduino core. You can program and use the Artemis module just like you would an Uno or any other Arduino. The time to first blink is just 5 minutes away! We built the core from the ground up, making it fast and as lightweight as possible.
Next is the module itself. Measuring 10 x 15 mm, the Artemis module has all the support circuitry you need to use the fantastic Ambiq Apollo3 processor in your next project. We're proud to say the SparkFun Artemis module is the first open-source hardware module with the design files freely and easily available. We've carefully designed the module so that implementing Artemis into your design can be done with low-cost 2-layer PCBs and 8mil trace/space.
Made in the USA at SparkFun's Boulder production line, the Artemis module is designed for consumer-grade products. This truly differentiates the Artemis from its Arduino brethren. Ready to scale your product? The Artemis will grow with you beyond the Uno footprint and Arduino IDE. Additionally, the Artemis has an advanced HAL (hardware abstraction layer), allowing users to push the modern Cortex-M4F architecture to its limit.
The SparkFun Artemis Module is fully FCC/IC/CE certified and is available in full tape and reel quantities. With 1M flash and 384k RAM, you'll have plenty of room for your code. The Artemis module runs at 48MHz with a 96MHz turbo mode available and with Bluetooth to boot!
A Guide to Powerful Programming for Embedded Systems
You must be a well-rounded professional to excel in the ever-evolving, rapidly developing embedded design and programming industry. Simply put, when it comes to electronics design and programming, the more topics you can master, the more you’ll flourish at your workplace and at your personal workbench. This shouldn’t be a surprise, as the line between the skills of a hardware engineer and software engineer is blurring. The former should have a good grasp of programming in order to build efficient systems. The latter should understand the details of the design (whether it’s a physical or virtual application) for which he or she is writing code. Thus, to be successful, a modern professional electronics engineer must have a solid grasp of both hardware design and programming.
Assembly Language Essentials is a matter-of-fact guide to Assembly that will introduce you to the most fundamental programming language of a processor. Unlike other resources about Assembly that focus exclusively on specific processors and platforms, this book uses the architecture of a fictional processor with its own hardware and instruction set. This enables you to consider the importance of Assembly language without having to deal with predetermined hardware or architectural restrictions.
You’ll immediately find this thorough introduction to Assembly to be a valuable resource, whether you know nothing about the language or you have used it before. The only prerequisite is that you have a working knowledge of at least one higher-level programming language, such as C or Java.
Assembly Language Essentials is an indispensible resource for electronics engineering professionals, academics, and advanced students looking to enhance their programming skills. The book provides the following, and more:
An introduction to Assembly language and its functionality
Significant definitions associated with Assembly language, as well as essential terminology pertaining to higher-level programming languages and computer architecture
Important algorithms that may be built into high-level languages, but must be done the “hard way” in Assembly language — multiplication, division, and polynomial evaluation
A presentation of Interrupt Service Routines with examples
A free, downloadable Assembler program for experimenting with Assembly

AVR Architecture and Programming An in-depth look at the 8-bit AVR architecture found in ATtiny and ATmega microcontrollers, mainly from a software and programming point of view. Explore the AVR architecture using C and assembly language in Microchip Studio (formerly Atmel Studio) with ATtiny microcontrollers. Learn the details of how AVR microcontrollers work internally, including the internal registers and memory map of ATtiny devices. Program ATtiny microcontrollers using an Atmel-ICE programmer/debugger, or use a cheap hobby programmer, or even an Arduino Uno as a programmer. Most code examples can be run using the Microchip Studio AVR simulator. Learn to write programs for ATtiny microcontrollers in assembly language. See how assembly language is converted to machine code instructions by the assembler program. Find out how programs written in the C programming language end up as assembly language and finally as machine code instructions. Use the Microchip Studio debugger in combination with a hardware USB programmer/debugger to test assembly and C language programs, or use the Microchip Studio AVR simulator. DIP packaged ATtiny microcontrollers are used in this volume for easy use on electronic breadboards, targeting mainly the ATtiny13(A) and ATtiny25/45/85. Learn about instruction timing and clocks in AVR microcontrollers using ATtiny devices. Be on your way to becoming an AVR expert with advanced debugging and programming skills.
With the availability of free and open source C/C++ compilers today, you might wonder why someone would be interested in assembler language. What is so compelling about the RISC-V Instruction Set Architecture (ISA)? How does RISC-V differ from existing architectures? And most importantly, how do we gain experience with the RISC-V without a major investment? Is there affordable hardware available?
The availability of the Espressif ESP32-C3 chip provides a way to get hands-on experience with RISC-V. The open sourced QEMU emulator adds a 64-bit experience in RISC-V under Linux. These are just two ways for the student and enthusiast alike to explore RISC-V in this book.
The projects in this book are boiled down to the barest essentials to keep the assembly language concepts clear and simple. In this manner you will have “aha!” moments rather than puzzling about something difficult. The focus in this book is about learning how to write RISC-V assembly language code without getting bogged down. As you work your way through this tutorial, you’ll build up small demonstration programs to be run and tested. Often the result is some simple printed messages to prove a concept. Once you’ve mastered these basic concepts, you will be well equipped to apply assembly language in larger projects.
The SQ series of handsfree PCBite probes from Sensepeek are insulated, come with included color-coded cable holders and have a lower point of gravity making them even more stable compared with the original SP series of probes. All the loved features of handsfree measurement, exchangeable fine pitch spring tipped test needle and the minimalistic design is maintained to make traditional sized and handheld probes obsolete.
Features
All handsfree probes from Sensepeek makes instant measurements or long triggering sessions a breeze.
No more soldering wires to connect your probe or complicated tools to setup, just positioning the probe needle on any test point or component in the signal path and release.
Saves time and frustration during development, verification and repairs.
The minimalist design and the spring-loaded test needle makes it possible to simultaneously measure on fine pitch components and nearby signals.
Both length and weight of the SQ probes are perfectly balanced to be used with PCBite PCB holders and base plate which is a must for handsfree function.
The probe holder comes with a powerful magnet in the base, as for all PCBite probes and holders which makes the probe easy to place and reposition.
The SQ series of probes can be used handheld without the probe holder as they have an insulated grip but their full potential is used when measuring handsfree.
Included
4x SQ10 probes and pin tipped test needles (black)
2x Banana to dupont test wires (red/black)
5x Dupont to dupont test wires
1x Set of cable holders (4 colors)
