From the project
Various printed circuit board projects
This PCB is an improved version of the mcutestboard PCB. RS485, better isolation, fan power output and mode.
This board follows on from the mcutestboard. The mcutestboard functions well, but quickly necessary improvements became evident to be able to fully service one axis of the satellite dish.
- PWM output. Isolated. - Encoder inputs. Isolated. - MCU will execute a PID loop. - Upgrade to the STM32G473CET6 LQFP48. Has 512KB Flash vs 128KB. - RS485. Isolated. With passthrough. - MCU controllerd 12V output for fan on/off. Isolated. - Requires only 12V input - I2C isolation - Onboard I2C…

Jrdish axis controller: common questions
What microcontroller does the Jrdish axis controller use?
The Jrdish axis controller is built around the STM32G474RET6, from the STM32 family.
How big is the Jrdish axis controller PCB?
The Jrdish axis controller measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Jrdish axis controller?
243 components, from 77 distinct parts. The full bill of materials is listed on this page.
Where can I download the Jrdish axis controller design files?
From the jrseti/pcbs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Jrdish axis controller design in my own project?
Yes, under the terms of its MIT license, which jrseti chose for the repository.
Can I test firmware for the Jrdish axis controller without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
