From the project

Ganglia is an open BLDC / brushed motor driver platform — custom PCB hardware plus STM32 firmware that runs a real-time control loop on top of FreeRTOS. It targets robotics joints and similar position/velocity controlled actuators, exposing the driver over Modbus (RS-485) and USB

Ganglia is an open BLDC / brushed motor driver platform — custom PCB hardware plus STM32 firmware that runs a real-time control loop on top of FreeRTOS. It targets robotics joints and similar position/velocity controlled actuators, exposing the driver over Modbus (RS-485) and USB CDC.

- MCU family: STM32F4 (STM32F405RG) or STM32F3 (STM32F303RC), selected at configure time - RTOS: FreeRTOS (CMSIS-RTOS port, CM4F/CM3) - Peripherals: ADC (current sensing), TIM (encoder + PWM), SPI (absolute encoder), USART/RS-485 (Modbus), USB CDC (debug console), IWDG - Control: PID position / velocity /…

Ganglia: common questions

How big is the Ganglia PCB?

The Ganglia measures 87 × 70 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ganglia?

200 components, from 70 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Ganglia design files?

From the H2O-Tnp/ganglia repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Ganglia design in my own project?

The repository has no license, so all rights stay with H2O-Tnp. Use it as a reference, and ask the author before reusing the design.
