About the EasyComm Board
EasyComm Board is an open source PCB design by stamina, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 70 × 80 mm, with 33 components from 17 distinct parts.
Other key parts include the Adafruit_Bluetooth, Adafruit_GPS, Adafruit_IMU and W25Q256JV. By type, the board carries 5 resistors, 4 ICs, 4 connectors, 2 LEDs, 1 transistor and 1 buzzer.
It belongs with the iot & wireless, rf & radio and sensors designs in this gallery.
From the project
Motorcycle ECU STM32 ARM Cortex 4 source code and hardware PCB design
EasyRider REV C is a motorcycle telemetrics project, developed specifically for my Honda C90 classic bike.
The software is written in C using the libopencm3 library for the STM32 446RE Arm Cortex M4 microcontroller.
The PCB's were created with Kicad 6, you'll find all gerbers/schematics/datasheets in the /docs directory.
EasyRider basically does the following things:
