Notes
Original 4032x3024 Wikimedia Commons field photo downloaded from File:Mch2022-badge.jpg, conservatively polygon-masked around the visible badge outline, scaled to the site badge canvas, and preserved as a transparent source cutout before WebP delivery conversion. This is a cropped documentary camp photo, not a studio packshot; partial field background remains where it is visible through or behind the badge in the original image. The published badge.gallery delivery file is an optimized WebP generated from the rights-cleared local derivative/source with metadata stripped, WebP quality 82, and a maximum side cap of 1600 pixels when the source is larger; upstream source URL, license, and attribution remain unchanged.

Why It Mattered

MCH2022 combined serious hardware with an accessible camp hacking workflow: nametag, games, BadgePython, app loading, sensor play, hardware expansion, and FPGA experiments.

Hardware

Badge.Team docs list ESP32 Wrover-E with 16 MB flash and 8 MB PSRAM, Raspberry Pi RP2040, Lattice iCE40UP5K FPGA, display, BNO055 orientation sensor, BME680 environmental sensor, SAO, Qwiic, PMOD, MicroSD, audio, IR, debug pads, and prototyping areas.

Software & Apps

Boots into an application chooser with nametag, BadgePython, sensor playground, Hatchery app loading/publishing, `mch22` hardware APIs, WebUSB FPGA loading, and ESP32/RP2040/FPGA firmware source trails.

Lore

The badge became a reference point for later discussions about what a camp badge should enable during the event itself: it was a Python app platform, game handheld, FPGA lab, sensor board, expansion host, and camp identity object at once.

Lifecycle

Add-ons & Upgrades

FPGA app historical

FPGA Peripheral demo

The FPGA Peripheral demo exposes the FPGA as an ESP32 peripheral with timer and random-number behavior, documenting the badge as a hardware experimentation platform.

Compatibility: MCH2022 Badge

Source
FPGA examples historical

iCE40 FPGA examples

The iCE40 firmware repository preserves FPGA examples and source that let the badge act as a learning platform for video, IO, and custom logic.

Compatibility: MCH2022 iCE40UP5K FPGA

Source
FPGA hardware expansion historical

PMOD FPGA expansion

The PMOD connector exposed FPGA-oriented IO for advanced hardware experiments beyond the application chooser and BadgePython surface.

Compatibility: MCH2022 iCE40UP5K FPGA

Source
FPGA tooling historical

WebUSB FPGA loader

The FPGA docs preserve a browser/WebUSB loading workflow for experimenting with the iCE40 fabric without treating FPGA development as ordinary app publishing.

Compatibility: MCH2022 iCE40UP5K FPGA

Source
Hatchery game app historical

Doom with sound

Henri Manson's app loads Doom on the ESP32 while using the FPGA for video and sound, turning MCH2022 into a handheld game-and-FPGA demonstration.

Compatibility: MCH2022 Badge

Source
app-store ecosystem historical

MCH2022 Hatchery app store

The MCH2022 Hatchery catalogue made app discovery and installation part of the camp badge workflow rather than a post-hoc source dump.

Compatibility: MCH2022 Badge

Source
board-management firmware historical

RP2040 co-processor firmware

The dedicated RP2040 firmware repository documents the badge's board-management co-processor as a separate maintained software component.

Compatibility: MCH2022 RP2040 co-processor

Source
hardware expansion historical

Qwiic I2C expansion

Qwiic gave badge hackers a documented I2C expansion path for sensor and breakout-board experiments.

Compatibility: MCH2022 Badge Qwiic connector

Source
hardware expansion historical

SAO expansion header

The extension-header docs preserve the badge's SAO surface, tying MCH2022 into the wider badgelife add-on ecosystem.

Compatibility: MCH2022 Badge SAO header

Source
hardware/software upgrade path historical

FPGA and accessory experiments

The badge's FPGA and RP2040/ESP32 split enabled deeper hardware experiments beyond ordinary app loading.

Compatibility: MCH2022 Badge

Source
radio/FPGA app historical

FPGA Morse 144MHz

The 144 MHz Morse app uses GPIO and FPGA behavior for a ham-radio-style badge experiment, broadening MCH2022 beyond ordinary MicroPython apps.

Compatibility: MCH2022 Badge with suitable external radio hardware

Source
software API historical

BadgePython mch22 APIs

BadgePython exposed an `mch22` module for badge-specific behavior such as display, LEDs, buttons, sensors, power, and peripherals.

Compatibility: MCH2022 BadgePython

Source
software add-on ecosystem historical

Hatchery apps

MCH2022 used Hatchery for app loading and publishing, making post-distribution applications part of the badge experience.

image provenance upgrade note

The MCH2022 page now uses a licensed original Wikimedia Commons documentary photo cut out to a transparent derivative and served as WebP.

The badge facts and visual provenance are now aligned: the image record preserves source URL, CC BY-SA 4.0 license, attribution, and cutout-processing notes.
