Development of a printed circuit board: STM32 + CH32V003 (RS485, CAN, HX711)
45 USD I have a task for the development of a printed circuit board: it is necessary to combine two existing circuits into one device for compactness.
The first board is created to read data from strain sensors to control an RGB LED strip.
This board consists of a CH32V003 microcontroller, a "MAX 485" module, an "HX711" module, and an LED driver (three transistors).
The second board consists of an STM32 microcontroller, a MAX485 module, and a CAN transceiver.
Both microcontrollers (CH32V003 and STM32) must be connected to a common RS485 bus directly on this board.
It is also necessary to properly route the analog part for the HX711 to avoid noise. The board should have mounting holes in specified locations and be within dimensions of up to 100 mm.
The schematic diagrams of the boards have already been developed; what is needed: verification and combination of the schematic diagrams, board routing, preparation of Gerber, BOM, and Pick&Place files for automated assembly (JLCPCB / PCBWay).

Client's review of cooperation with Pavlo D.
Development of a printed circuit board: STM32 + CH32V003 (RS485, CAN, HX711)Pavlo seemed competent at first, raised the fee but it did not meet the technical requirements. After a brief discussion, he agreed to redo it, but after that, he stopped responding. In the end, he did not complete the order.

Hello! The project is clear and looks very interesting. I have experience working with budget microcontrollers from the CH32 series as well as with STM32, and also in designing mixed signal boards (Analog/Digital).

В чем сделан проект?
-
EasyEDA, можу експортувати до Altium або PADS якщо потрібно
-
Та не, он удобен сразу для заказа на jlcpcb, даже с монтажем и ценами на компоненты из каталога basic.

Ви вказуєте мікроконтролер, але на плати у вас модуль. Так а що таки потрібно мати на виході?
