Name: VESC Rmcore
SKU: VESC-ACC-RMCORE
Price: 39.99 EUR
Availability: InStock

The VESC Rmcore is a small PCB with 4 analog inputs, 4 switched outputs, USB, and CAN-bus. It can be used as a CAN-connected or wireless IO expander for connecting peripherals such as throttles, brake switches, buttons, lights, and indicators. All functions can be scripted in LispBM from VESC Tool while connected over USB or wirelessly using Wi-Fi or Bluetooth 5.

The VESC Rmcore is a compact IO expansion module designed for VESC-based systems, featuring 4 analog inputs, 4 switched outputs, Wi-Fi, Bluetooth 5, and CAN-bus communication. It can operate as either a CAN-connected or wireless IO expander, making it ideal for integrating peripherals such as throttles, brake switches, buttons, headlights, indicators, and displays.

All functionality can be fully customized using LispBM scripts directly in VESC Tool, with programming and configuration available over USB, Wi-Fi, or Bluetooth 5.

Suggested applications:

Handlebar-mounted IO expansion for scooters and e-bikes
Simplified vehicle wiring with peripherals connected through a single module
Custom wired or wireless remote controls
Lighting and accessory control over CAN-bus

By placing the Rmcore close to user controls or accessories, system wiring can be reduced to just 4 wires between the motor controller and the remote module.

Please note that this device currently can only be configured through LispBM scripting.
Please see the product datasheet for further details.

Important
We have not received the correct cables and connectors for the RMCORE yet, so the early units will ship with cables that have the wrong colors.
Please ignore the cable colors and check the pinout in the datasheet before connecting!

Can I use UAVCAN or DroneCAN on my device?

When changing CAN-mode to UAVCAN (DroneCAN) the VESC CAN protocol will be disabled. This means that VESC Tool can’t be used to configure and monitor ESCs or other VESC devices on the CAN-bus at the same time as UAVCAN is enabled. This is especially a problem on the Maxim, Pronto and Duet controllers as they access the STM32 using the ESP32 using VESC CAN. The later firmwares will therefore switch back to VESC CAN on reboot.

Earlier firmwares will not switch back on reboot, meaning that it is possible to lock yourself out from them (Maxim, Pronto and Duet) when changing to UAVCAN. If you have locked yourself out you can either try connecting using the UART-port with an USB-to-UART adapter and 115200 baudrate or you can use USB to reflash the STM32.

So, how do I use UAVCAN on Maxim, Pronto or Duet? Unfortunately we don’t have a good solution for that now. As it is now UAVCAN is not widely used among our customers (and VESC-users in general), but if it becomes more popular we will look into improving UAVCAN-support in the firmware. Pull-requests on github are always welcome of course!
