AngstromIO: Compact 9.0 x 8.9 mm ATtiny1616 Board for USB-C Connector

AngstromIO ATtiny1616 tiny USB-C development board

Dieu-de-l-elec’s AngstromIO is an incredibly tiny open-source development board based on Microchip’s ATtiny1616 MCU. Measuring just 9.0 x 8.9 mm, the board is barely larger than the edge-mounted USB Type-C connector that powers it, making it ideal for highly space-constrained embedded projects. Despite its tiny footprint, AngstromIO packs a QFN20-packaged ATtiny1616 MCU, two addressable SK6805-EC15 RGB LEDs, and includes access to various usable GPIOs, including I2C, UART, and UPDI for programming. AngstromIO specifications: MCU – Microchip ATtiny1616 8-bit AVR microcontroller @ up to 20 MHz with 16KB flash, 2KB SRAM, 256 bytes EEPROM USB – 1x USB Type-C port (power only, no data lines connected to the MCU) Expansion via solder pads UPDI pin for programming I2C (SDA, SCL) 2x GPIOs (PB2/TX, PA3) 5V and GND Misc – 2x SK6805-EC15 addressable RGB LEDs Power Supply 5V via USB-C port Ultra-low power consumption (down to 200nA in power-down mode) Dimensions – 9.0 […]
