About the EdgeSense PCB

EdgeSense is an open source STM32 PCB design by Circuit-Digest, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 38.5 × 31 mm, with 58 components from 32 distinct parts.

Its main chip is the STM32H533CEU6, from the STM32 family. Other key parts include the VL53L8CHV0GC/1, ST1L08SPU33R, L6924D013TR, LD1117V18 and ST2378ETTR. By type, the board carries 25 capacitors, 17 resistors, 6 ICs, 4 connectors, 2 crystals and 2 switches.

STM32 Edge AI Texture and Gesture Classifier

# EdgeSense: STM32 Edge AI Texture and Gesture Classifier

EdgeSense is a compact, high-performance edge artificial intelligence platform that performs on-device 3D gesture recognition, surface/texture classification, static hand posture detection, and optical obscuration sensing.

Powered by the STM32H533CEU6 (ARM Cortex-M33 running at 250 MHz) and the ST VL53L8CH 8x8 direct Time-of-Flight (dToF) sensor, EdgeSense executes quantized neural networks entirely on-chip in real time with sub-7 ms inference latency.

EdgeSense: common questions

What microcontroller does the EdgeSense use?

The EdgeSense is built around the STM32H533CEU6, from the STM32 family.

How big is the EdgeSense PCB?

The EdgeSense measures 38.5 × 31 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EdgeSense?

58 components, from 32 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 EdgeSense design files?

From the Circuit-Digest/EdgeSense repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the EdgeSense design in my own project?

Yes, under the terms of its GPL-3.0 license, which Circuit-Digest chose for the repository.

Can I test firmware for the EdgeSense 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.
