Lora technology and Lora devices have been widely used in the field of the Internet of Things (IoT), and more and more people are joining and learning Lora development, making it an indispensable part of the IoT world. To help beginners learn and develop Lora technology better, a Lora development board has been designed specifically for beginners, which uses RP2040 as the main control and is equipped with the RA-08H module that supports Lora and LoRaWAN protocols to help users realize development. RP2040 is a dual-core, high-performance, and low-power ARM Cortex-M0+ architecture chip, suitable for IoT, robots, control, embedded systems, and other application fields. RA-08H is made from the Semtech-authorized ASR6601 RF chip, which supports the 868 MHz frequency band, has a 32 MHz MCU built-in, which has more powerful functions than ordinary RF modules, and also supports AT command control. This board retains various functional interfaces for development, such as the Crowtail interface, the common PIN to PIN header that leads out GPIO ports, and provides 3.3 V and 5 V outputs, suitable for the development and use of commonly used sensors and electronic modules on the market. In addition, the board also reserves RS485 interface, SPI, I²C, and UART interfaces, which can be compatible with more sensors/modules. In addition to the basic development interfaces, the board also integrates some commonly used functions, such as a buzzer, a custom button, red-yellow-green three-color indicator lights, and a 1.8-inch SPI interface LCD screen with a resolution of 128x160. Features Uses RP2040 as the main controller, with two 32-bit ARM Cortex M0+ processor cores (dual-core), and provides more powerful performance Integrates the RA-08H module with 32 MHz MCU, supports the 868 MHz frequency band and AT command control Abundant external interface resources, compatible with Crowtail series modules and other common interface modules on the market Integrates commonly used functions like buzzer, LED light, LCD display and custom button, making it more concise and convenient when creating projects Onboard 1.8-inch 128x160 SPI-TFT-LCD, ST7735S driver chip Compatible with Arduino/Micropython, easy to carry out different projects Specifications Main Chip Raspberry Pi RP2040, built-in 264 KB SRAM, onboard 4 MB Flash Processor Dual Core Arm Cortex-M0+ @ 133 MHz RA-08H Frequency band 803-930 MHz RA-08H Interface External antenna, SMA interface or IPEX first-generation interface LCD Display Onboard 1.8-inch 128x160SPI-TFT-LCD LCD Resolution 128x160 LCD Driver ST7735S (4-wire SPI) Development environment Arduino/MicroPython Interfaces 1x passive buzzer 4x user-defined buttons 6x programmable LEDs 1x RS485 communication interface 8x 5 V Crowtail interfaces (2x analog interfaces, 2x digital interfaces, 2x UART, 2x I²C) 12x 5 V universal pin header IO 14x 3.3 V universal pin header IO 1x 3.3 V/5 V switchable SPI 1x 3.3 V/5 V switchable UART 3x 3.3 V/5 V switchable I²C Working input voltage USB 5 V/1 A Operating temperature -10°C ~ 65°C Dimensions 102 x 76.5 mm (L x W) Included 1x Lora RA-08H Development Board 1x Lora Spring Antenna (868 MHz) 1x Lora Rubber Antenna (868 Mhz) Downloads Wiki

A low-power, open source, 2.7-inch IoT display powered by an ESP32-S2 module and featuring SHARP's Memory-in-Pixel (MiP) screen technology The Newt is a battery-powered, always-on, wall-mountable display that can go online to retrieve weather, calendars, sports scores, to-do lists, quotes…really anything on the Internet! It is powered by an ESP32-S2 microcontroller that you can program with Arduino, CircuitPython, MicroPython, or ESP-IDF. It's perfect for makers: Sharp’s Memory-in-Pixel (MiP) technology avoids the slow refresh times associated with E-Ink displays A real-time clock (RTC) was added to support timers and alarms The Newt was designed with battery operation in mind; every component on the board was chosen for its ability to operate at low power. Newt was designed to operate 'untethered,' which means it can be mounted in places where a power cord would be inconvenient, for example a wall, refrigerator, mirror, or dry-erase board. With the optional stand, desks, shelves, and nightstands are also good options. Newt is open source, and all design files and libraries are available for review, use, and modification. However, doing that is not required. Each Newt is delivered with working code with the following features: Current weather details Hourly and daily weather forecast Alarm Timer Inspirational quotes Air-quality forecast Habit calendar Pomodoro timer Oblique Strategy cards Only following the Wi-Fi provisioning instructions is needed to get started. No app downloads are required.
