PacketChat/MonkeyBadge21This repository contains the hardware design files, badge code, and backend infrastructure code for the HushCon Winter 2023 badge.
Monkeys is an open-source printed circuit board by PacketChat, from the PacketChat/MonkeyBadge repository on GitHub. It is a 2-layer board of 144.9 × 59.8 mm with 153 parts on 130 nets, routed with 2,519 tracks and 339 vias.
It is built around the CH340C, LM4808M and SI4702-C19-GM, with the BQ24072RGTR, RT9080-33GJ5 and SK6812D-EC3210R among its other parts. Its parts include 46 capacitors, 37 resistors, 12 diodes, 9 ICs and 7 switches. It belongs with the ESP32 boards of this library.
This repository contains the hardware design files, badge code, and backend infrastructure code for the HushCon Winter 2023 badge.
The code for the badge is based on [Micropython][1]. For full documentation read the datasheet, comments, and commit history.
The api-server is the backend gameserver it provides an API interface for the badge to save state and complete challenges.
You will need a redis server with the json mod, docker run -d -p 6379:6379 redislabs/redismod works fine.
This is based on FastAPI and is easily executed with: cd api-server; python3 api-server
Built, with Flask

It measures 144.9 × 59.8 mm and has 2 copper layers, 1.6 mm thick.
153 parts, built around the CH340C, LM4808M, SI4702-C19-GM and BQ24072RGTR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the PacketChat/MonkeyBadge repository on GitHub, at the commit this page was made from: the board is pcb_design/Monkeys.kicad_pcb and its schematic pcb_design/Monkeys.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask PacketChat before reusing the design.
