About the Electronic Load PCB

Electronic Load is an open source STM32 PCB design by Synthron, published on GitHub. It is a 4-layer board measuring 160 × 100 mm, with 102 components from 41 distinct parts.

Its main chip is the STM32F103C8Tx, from the STM32 family. Other key parts include the AP1117-33, L79L05_SO8, SN65HVD232, LM35-LP and LM2904. By type, the board carries 43 capacitors, 30 resistors, 8 ICs, 7 connectors, 5 transistors and 5 diodes.

It belongs with the audio and displays & leds designs in this gallery.

From the project

Modular Electronics Workstation

The ModLab is designed to be housed in a 19" Rack with 3U. It is the improved version of the (failed) Arduino Workstation I built a long time ago.

But now It will be bigger, better and way too complicated.

Electronic Load: common questions

What microcontroller does the Electronic Load use?

The Electronic Load is built around the STM32F103C8Tx, from the STM32 family.

How big is the Electronic Load PCB?

The Electronic Load measures 160 × 100 mm, has 4 copper layers and is 1.56 mm thick.

How many components are on the Electronic Load?

102 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Electronic Load design files?

From the Synthron/ModLab repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Electronic Load design in my own project?

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

Can I test firmware for the Electronic Load 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.
