## Overview
|
|
|
|
DynaLoRa-USB is a low cost and open source, CircuitPython and Arduino compatible, LoRa tinkering dongle designed by and for makers.
|
|
|
|
Our aim is to facilitate access to the hottest radio technology (LoRa) through the use of maker-friendly languages such as Python and the Arduino framework. With that intent, DynaLoRa-USB is a simple device that you just plug and play with! It includes a powerful SAMD21 microcontroller and a HopeRF LoRa radio module (RFM96W for 868/915 MHz), an user button, an RGB LED and an external interface to plug your favorite peripherals.
|
|
|
|
|
|
- ATSAMD21E18 48 MHz Cortex-M0+ processor with 256 KB flash + 32 KB RAM, compatible with CircuitPython and Arduino
|
|
- 32 Mbit SPI flash for storing CircuitPython code and libraries
|
|
- High performance HopeRF radio module. We offer the device with the RFM96W, which is capable of LoRa modulation at 868/915 MHz, but you can easily replace it by the 433 MHz version (RFM95W) or a generic Sub-GHz radio (RFM69HCW) since they are pin compatible.
|
|
- User-controllable WS2812B addressable RGB LED
|
|
- Regular user LED
|
|
- 3V3 @ 1A power through a DC/DC buck regulator from USB
|
|
- MicroSD Card slot
|
|
- GPIO header exposing SWD interface, a full SERCOM (enabling external SPI/I2C/UART peripherals) and a DAC for prototyping
|
|
- This version comes with an USB-A plug. It should be easy enough to modify the design to offer other options (such as USB-C).
|
|
- Comes preprogrammed with the UF2 Bootloader and latest stable release of CircuitPython.
