Aludel is a PCB base that accepts any microcontroller board that uses the Feather standard. Golioth created this to make hardware “swapability” possible, while using Zephyr to manage the firmware.
During the current chip shortage, this allows for using the Feather microcontroller boards that fit the project and are available.
Chris Gammell centered the design around a readily available industrial enclosure. The core concept is a PCB base that accepts any microcontroller board that uses the Feather standard. This way, every pin-location and function is standardized. Alongside the Feather you’ll find two headers that use the Click boards standard (PDF), a footprint for expansions boards facilitating I2C, SPI, UART, and more. The base includes Qwiic and Stemma headers for additional sensor connectivity, as well as terminal blocks, room for a battery, and provisions for external power.
The beauty of this is that electrically, it all just works. Need an nRF52, nRF9160, ESP32, STM32, or RP2040? They all already exist in Feather form factor. Need to change the type of temperature sensor you’re using? Want to add RS485, CANbus, MODBUS, 4-20 ma communication, or some other connectivity protocol? The hardware is ready for it.
