The DIY Mini Digital Oscilloscope Kit (with shell) is an easy-to-build kit for a tiny digital oscilloscope. Besides the power switch, it has only one other control, a rotary encoder with a built-in pushbutton. The kit's microcontroller comes preprogrammed. The 0.96" OLED display has a resolution of 128 x 64 pixels. The oscilloscope features one channel that can measure signals up to 100 kHz. The maximum input voltage is 30 V, the minimum voltage is 0 V.
The kit consists of through-hole components (THT) are surface-mount devices (SMD). Therefore, assembling the kit means soldering SMD parts, which requires some soldering experience.

The MicroMod DIY Carrier Kit includes five M.2 connectors (4.2mm height), screws, and standoffs so that you can get all the special parts you may need to make your own carrier board.
MicroMod uses the standard M.2 connector. This is the same connector found on modern motherboards and laptops. There are various locations for the plastic ‘key’ on the M.2 connector to prevent a user from inserting an incompatible device. The MicroMod standard uses the ‘E’ key and further modifies the M.2 standard by moving the mounting screw 4mm to the side. The ‘E’ key is fairly common so a user could insert an M.2 compatible Wifi module. Still, because the screw mount doesn’t align, the user would not secure an incompatible device into a MicroMod carrier board.

The ESP32-PICO-Kit fits into a mini breadboard. It is fully functional with the minimum number of discrete components, while it has all the ESP32 pins exposed.
Features
Complete up-to-date documentation is available.
All instructions and commands presented work as described.
Plentiful additional information and hardware documentation are available too.
Applications for the ESP32-PICO-KIT can be developed on Windows, Linux or Mac.
Two cores and a radio
Like the ESP8266 the ESP32 has Wi-Fi but adds Bluetooth. It also has two 32-bit cores inside, making it extremely powerful, and providing all the ports and interfaces that the ESP8266 is lacking.Oversimplifying things, one might say that the ESP8266 is a Wi-Fi controller that provides some I/O, whereas the ESP32 is a full-fledged controller that also has Wi-Fi.
ESP32 peripherals
The ESP32 exposes an ADC & DAC, touch sensor circuitry, an SD/SDIO/MMC host controller, an SDIO/SPI slave controller, an EMAC, PWM to control LEDs and motors, UART, SPI, I²C, I²S, infrared remote controller, and, of course, GPIO.
ESP32-PICO-KIT Development board
The ESP32-PICO-D4 is a System-on-Chip (SoC) integrating an ESP32 chip together with a 4 MB SPI flash memory in a tiny 7 x 7 mm package.
The ESP32-PICO-KIT is a breakout board for this SoC with an onboard USB-to-serial converter for easy programming and debugging.
Besides the board, you'll need a programming toolchain. Complete, up-to-date documentation from Espressif is available on the Read the Docs website.
All instructions and commands presented work as described.Plentiful additional information and hardware documentation are available too.
Applications for the ESP32-PICO-KIT can be developed on Windows, Linux or Mac.
Reinforcing its commitment to widening the accessibility to and innovation in the area of deep learning, NVIDIA has created a free, self-paced, online Deep Learning Institute (DLI) course, “Getting Started on AI with Jetson Nano.” The course's goal is to build foundational skills to enable anyone to get creative with the Jetson Developer Kit. Please be aware that this kit is for those who already own a Jetson Nano Developer Kit and want to join the DLI Course. A Jetson Nano is not included in this kit.
Included in this kit is everything you will need to get started in the “Getting Started on AI with Jetson Nano” (except for a Jetson Nano, of course), and you will learn how to
Set up your Jetson Nano and camera
Collect image data for classification models
Annotate image data for regression models
Train a neural network on your data to create your own models
Run inference on the Jetson Nano with the models you create

Build Your Own Vintage Radio Broadcaster
The Elektor AM Transmitter Kit allows streaming audio to vintage AM radio receivers. Based on a Raspberry Pi Pico microcontroller module, the AM Transmitter can transmit on 32 frequencies in the AM band, from 500 kHz up to 1.6 MHz in 32 steps of approx. 35 kHz.
The frequency is selected with a potentiometer and shown on a 0.96" OLED display. A pushbutton allows toggles the transmitting mode between On and Off. The range of the transmitter depends on the antenna. The onboard antenna provides a range of a few centimeters, requiring the AM Transmitter to be placed close to or inside the radio. An external loop antenna (not included) can be connected to increase the range.
The Elektor AM Transmitter Kit comes as a kit of parts that you must solder to the board yourself.
Features
The board is compatible with a Hammond 1593N enclosure (not included).A 5 VDC power supply with micro-USB connector (e.g., an old phone charger) is needed to power the kit (not included). Current consumption is 100 mA.
The Arduino software (requiring Earle Philhower’s RP2040 Boards Package) for the Elektor AM Transmitter Kit plus more information is available at the Elektor Labs page of this project.

Schematic
The matte-black circuit board is extra thick and has subtle white markings, including an alphanumeric grid and PIN labels. The wiring pattern – that of classic breadboards – is easy to see by looking at the exposed traces on the bottom of the board.
The kit comes complete with the 'Integrated Circuit Leg' stand and 8 colour-coded thumbscrew terminal posts. Using the terminal posts and solder points, you can hook up to your 'IC' with bare wires, lugs, alligator clips, and/or solder joints. Connections to the 8 terminal posts are through the three-position strips on the PCB; each is labelled with the corresponding PIN.
