Lifecycle

Add-ons & Upgrades

MCH2022 Badge historical

FPGA app

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

MCH2022 Badge historical

FPGA examples

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

MCH2022 Badge historical

FPGA hardware expansion

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

MCH2022 Badge historical

FPGA tooling

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

MCH2022 Badge historical

Hatchery game app

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

MCH2022 Badge historical

app-store ecosystem

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

MCH2022 Badge historical

board-management firmware

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

MCH2022 Badge historical

hardware expansion

Qwiic I2C expansion

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

Compatibility: MCH2022 Badge Qwiic connector

MCH2022 Badge historical

hardware expansion

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

MCH2022 Badge historical

hardware/software upgrade path

FPGA and accessory experiments

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

Compatibility: MCH2022 Badge

MCH2022 Badge historical

radio/FPGA app

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

MCH2022 Badge historical

software API

BadgePython mch22 APIs

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

Compatibility: MCH2022 BadgePython

MCH2022 Badge historical

software add-on ecosystem

Hatchery apps

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

Compatibility: MCH2022 Badge

Operational history

Issues & Camp Impact

MCH2022 Badge note

FPGA tooling barrier · primary docs · documented caveat

FPGA development had a separate workflow from normal Hatchery apps, including examples, dedicated repositories, and a WebUSB loading path.

MCH2022 was accessible as a Python app badge, but its FPGA surface required a higher hardware-tooling skill level.

MCH2022 Badge note

documentation lifecycle · primary docs · historical/current archive

MCH2022 details are split across Badge.Team docs, Hatchery app pages, GitHub firmware repositories, and technical media coverage.

The compendium treats MCH2022 as a platform record with multiple source trails rather than a single static badge page.

MCH2022 Badge note

extension pinout care · primary docs · documented caveat

The expansion docs split Qwiic, SAO, PMOD, IR, GPIO, and debug surfaces into separate pinout records, which users needed to follow before attaching hardware.

The badge exposed rich expansion hardware, but safe use depended on reading the correct connector documentation.

MCH2022 Badge note

image provenance upgrade · licensed source photo · licensed original replacement applied

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.

MCH2022 Badge note

multi-processor complexity · primary docs and repositories · documented

The badge combined ESP32, RP2040, and iCE40 software stacks, each with its own repository or workflow.

The architecture enabled unusual experiments but makes firmware provenance and troubleshooting more complex than a single-MCU badge.
