Required hardware

BOARD

• M5STACK CORE2 IOT Development Kit (K010) https://shop.m5stack.com/products/m5stack-core2-esp32-iot-development-kit
• older M5STACK CORE2 IOT Development Kit (K010) https://shop.m5stack.com/products/m5stack-core2-esp32-iot-development-kit

CAN vs OBD2 adapter

• optional CAN module COMMU (M011) - RS485, TTL and CAN https://shop.m5stack.com/products/commu-module

• OBD2 connector can provide power to the M5 stack with a 12V to 5V converter (e.g. Recom R-785.0-1.0).

• OBD2 adapters - supported is only Vgate iCar Pro Bluetooth 4.0 (BLE4) OBD2. We can add another BLE adapter if you provide 3x UUID (service/notify,read/write)

• For nonstop use we strongly recommend to use direct CAN onnection (via OBD2 connector)). It's due to security!

GPS

• GNSS Module with Barometric Pressure, IMU, Magnetometer Sensors (NEO-M9N, BMP280, BMI270, BMM150) https://shop.m5stack.com/products/gnss-module-with-barometric-pressure-imu-magnetometer-sensors
• older module (M003) - NEO-M8N (with external atenna) https://shop.m5stack.com/products/gps-module

Hardware configuration

The M5 Core 2 uses UART0 for serial communication and flashing (USB port).

The COMMU module is wired with SMD jumpers to use UART0 for TTL and UART2 for RS485. CAN doesn't need UART. Both 0 and 2 can be unwired.

The GPS module is wired with SMD jumpers to use UART2. This can be easily changed to UART0 in order to use it stacked with the GSM module. The counterside is this conflicts with the USB connection of Core2, so flashing will not be possible.If it's only stacked with COMMU, it can stay on UART2, but COMMU needs to be unwired from UART2.

Check the documentations of the modules for more details: Core2 - https://docs.m5stack.com/en/core/core2 GPS - https://docs.m5stack.com/en/module/gps COMMU - https://docs.m5stack.com/en/module/commu
