Universus VCU


Universus VCU (Vehicle Control Unit) is our own product used for connected electric vehicles (e-bikes, mopeds, scooters). Universus is based on PIC32 MCU from Microchip and it uses WiFi or Bluetooth connection. Universus is an I/O module with various I/O port types, like insulated inputs, analog measurement, binary outputs, RS485 communication ports, and DAC-based power regulators. The first version of our Grunner bike used this module for offline controls.


  • I/O ports
  • RS485, Modbus protocol
  • DAC


  • ESP8266 (Later upgraded to ESP32)
  • PIC32
  • C/C++
  • Hardware development and production

The work

The product was developed to fulfill the need on the market for smart electric bikes.

The Outcome

All modules that have been produced are still fully operational in Grunner smart electric bikes.
