Protopoint
About the Protopoint PCB
Protopoint is an open source STM32 PCB design by lab11, published on GitHub under the Apache-2.0 license. It is a 4-layer board measuring 31.8 × 27.5 mm, with 57 components from 27 distinct parts.
Its main chip is the STM32F031G6U6, from the STM32 family. Other key parts include the LXDC2HL, DW1000, SKY13317, ProtoPoint_Module and AO6604. By type, the board carries 40 capacitors, 7 ICs, 7 resistors, 2 crystals and 1 transformer.
It belongs with the iot & wireless designs in this gallery.
From the project
Indoor localization based on the DecaWave DW1000.
The PolyPoint system consists of several PCBs centered around TriPoint, the core UWB ranging module.
1. TriPoint: Triangular module which contains all necessary hardware for using the DecaWave DW1000. It has castellated headers so it can be soldered onto a carrier board to add indoor localization functionality to any device.
2. TriTag: Portable carrier board designed to be used as an indoor localization tag. Has TriPoint on one side and a BLE radio on the other.

Protopoint: common questions
What microcontroller does the Protopoint use?
The Protopoint is built around the STM32F031G6U6, from the STM32 family.
How big is the Protopoint PCB?
The Protopoint measures 31.8 × 27.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Protopoint?
57 components, from 27 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 Protopoint design files?
From the lab11/polypoint repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Protopoint design in my own project?
Yes, under the terms of its Apache-2.0 license, which lab11 chose for the repository.
Can I test firmware for the Protopoint 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.
