what do you think about a speeduino's project in 2 pcb ?
I mean (based on an enclosure like DROPBEAR):
1 daughter pcb including all functions (8INJ, 8ING, IDLE, VVT, ...) + all filtering and modulation signals (CAM, CRANK, IAT, MAP, BARO, TPS, EGT, WBOx Ubat, IDLE) + AUTOMOTIVE CONNECTORS like DROPBEAR;
1 motherboard pcb with MCU but with standard numbers and peripherical position connectors to daughter board, 5v + BT or CAN signals, etc ...; with the ability to connect to various locations designed for MCU TEENSY3.X or TEENSY4.X or MEGA or ARDUINO PRO or STM32?
Isn't this a way to ensure that MCU availability won't be an issue?
Kind regards, Julien.
