MCH2022 badge sneak previews from tweeps that attended the Bitlair 20220709 Sweatshop (@MCH2022Camp)

Posted by jpluimers on 2022/07/10

The MCH2022 badge has an ESP32 (with WiFi!), a RP2040 and an FPGA next to a full colour TFT LCD, buttons (including joystick!), LEDs, LiPo battery, USB-C connector, micro SD-card slot and more (see below) and SHA2017 badge compatibility. How cool is that!

There is a wealth on information for this at [Wayback/Archive] (some 22 repositories and counting: [Wayback/Archive] search for repositories containing mch2022).

Good starts are [Wayback/Archive] MCH2022 badge | BADGE.TEAM and [Wayback/Archive] Software Development | BADGE.TEAM (yes of course you can write your own software for it and even distribute it through the [Wayback/Archive] Hatchery).

Below are lots of tweets including some of the Twitter retrospect that organically grew (just like the sweatschop event) on Twitter the day after.

From the original announcement [Wayback/Archive] May Contain Hackers 2022: Presenting: The MCH2022 badge! , this is what hardware is in it


  • Espressif ESP32 Wrover-E with 16MB of flash storage and paired with 8MB of PSRAM, for front-end badge computing and compatibility with the ecosystem back to the 2017 SHA badge.
  • Lattice ICE40UP5K FPGA for hardware-accelerated graphics and user FPGA hardware designs.
  • Raspberry Pi RP2040 for advanced USB communication and board management.
  • 2Ah LiPo battery to give you a full day of fun on a charge.
  • 16-bit DAC with stereo output to headphone socket, onboard mono speaker.
  • ILI9341 2.2 inch TFT display with a 240 by 320 pixel resolution.
  • Bosch BNO055 orientation sensor.
  • Bosch BME680 environmental sensor.
  • The usual array of addressable LEDs.
  • SAO and Qwiic expansion connectors, FPGA PMOD expansion, plus onboard prototyping area.

The flashing event

I got one as a thank-you gesture after participating in the [Wayback/Archive] Events/2022-07-09 MCH2022 Badge Flashing Sweatshop – Hackerspace Amersfoort (more details at [Wayback/Archive] Team:Badge/Sweatshops – MCH2022 wiki: Flashing sweatshop).

There are no overview photo’s of the event itself, but the below one is one from the prior event, the [Wayback/Archive] Events/2022-07-02 MCH2022 Badge Packaging Sweatshop – Hackerspace Amersfoort (with details at [Wayback/Archive] Team:Badge/Sweatshops – MCH2022 wiki):

MCH2022 Web site

Unlike the hardware side (which is on GitHub), the web side is on GitLab: [Wayback/Archive] maycontainhackers · GitLab. I like both environments (they have different strengths and weaknesses) at [Wayback/Archive] maycontainhackers / MCH2022 Website · GitLab.

Visit the site at [Wayback/Archive] May Contain Hackers 2022.

Teaser Videos

The below video was posted by Jilles earlier today in a great thread that contained [Wayback/Archive] 🔜 MCH2022 🏳️‍🌈🏳️‍⚧️ on Twitter: “Video” [Wayback/Archive]… (if not visible: click on the above Tweet or the Wayback Machine link on the left)

In a separate message, he also posted about the [Wayback/Archive] 🔜 MCH2022 🏳️‍🌈🏳️‍⚧️ on Twitter: “FPGA selftest” resulting in the video I archived at [Wayback/Archive]…:

I added the first thread in full to [Wayback/Archive] Thread by @jilles_com on Thread Reader App. It starts with [Wayback/Archive] 🔜 MCH2022 🏳️‍🌈🏳️‍⚧️ on Twitter: “Hackers Woodstock: @MCH2022Camp July 22nd – 26th, 2022 Still a few tickets available, Book now or wait 4 years for the next one.

And yes you can still book tickets at the [Wayback/Archive] MCH2022 ticketshop.

Media coverage

How it all came

If you want to know more about the back-story and process, then start at [Wayback/Archive] Team:Badge – MCH2022 wiki and [Wayback/Archive] BADGE.TEAM documentation | BADGE.TEAM as the team has been creating marvelous badges for quite a few events already.

Some archived tweets

Be sure to watch the other messages about organising events like these. Lots you can learn from them too.

One of the first teasers: [Wayback/Archive] 🔜 MCH2022 🏳️‍🌈🏳️‍⚧️ on Twitter: “It comes with an EPIC Badge”

Since the hatchery NG is not yet done:

It is open source, so if you have a feature request you can try to make a pull request: [Wayback/Archive] Reinier on Twitter: “@KirilsSolovjovs @jilles_com @MCH2022Camp PRs for more themes are welcome ;)”

There are hardware headers for SAO* and PMOD (both through hole) and switch (surface mount), Reinier explained about the PMOD:

[Wayback/Archive] Reinier on Twitter: “@jilles_com @MCH2022Camp For PMOD, there is space for an angled female header so it doesn’t stick out from the back of the badge :)”

*SAO = [Wayback/Archive] Simple Add-ons (SAO) |

and Jilles went wild today:

  1. [Wayback/Archive] 🔜 MCH2022 🏳️‍🌈🏳️‍⚧️ on Twitter: “Hardware Hackers: Since the @MCH2022Camp badge features a PMOD & SAO fanout. You can add many of the online available PMOD extensions. Don’t forget to bring a female header: 6×2 2.54 for PMOD 3×2 2.54 for SAO These are features for people who want to upgrade their badge!”

  2. [Wayback/Archive] 🔜 MCH2022 🏳️‍🌈🏳️‍⚧️ on Twitter: “Time to do some soldering… “

  3. [Wayback/Archive] 🔜 MCH2022 🏳️‍🌈🏳️‍⚧️ on Twitter: “Done”

  4. [Wayback/Archive] 🔜 MCH2022 🏳️‍🌈🏳️‍⚧️ on Twitter: “How my mind works in 4 simple steps:”

  5. [Wayback/Archive] 🔜 MCH2022 🏳️‍🌈🏳️‍⚧️ on Twitter: “#HardwareHacker #PMOD”

  6. [Wayback/Archive] 🔜 MCH2022 🏳️‍🌈🏳️‍⚧️ on Twitter: “PMOD for FPGA done. #GhettoStyle”

Jilles even checked out the test pads:

My own pictures are in these tweets:

Where to go from here

Find way (and likely increasingly) more via [Wayback/Archive] mch2022 badge – Google Search.
