Thanks @AstonJ! This has been an ongoing saga, and it all started with this talk 
Unfortunately, Google has got it a little bit wrong on the chip details. The specs and datasheet for this chip can be found here. The highlights: it has two ARM A7 core @ 1GHz, 256MB DDR3, and a pretty good selection of peripherals for a chip of this size (I2C, UART, SPI, CAN, SDIO, Ethernet, LVDS, RGB888, etc). It’s definitely a fun chip to use with Nerves!
Trellis is a project to make designing custom hardware with Nerves more accessible. The design is open source, created with open source PCB design tools

After ElixirConf EU last year, @lawik and I cooked up a plan to make a Trellis variant for the Goatmire conference last September in Sweden. We managed to pull it off, and thanks to a sponsor covering all the hardware costs, everyone who attended received a Nerves-powered e-ink name badge:
- Hardware repo: GitHub - protolux-electronics/wisteria_hardware: Hardware files for Wisteria, the Nerves e-ink name badge · GitHub
- Firmware: GitHub - protolux-electronics/name_badge: Software to run on the Nerves name badge, as given out at Goatmire 2025 · GitHub
Now, I’m working on developing the new Nerves Starter Kit, which is a piece of first-party hardware for the Nerves ecosystem. It’s similar to the name badge, but with a larger display, onboard sensors, low power mode and plenty more improvements. Release date later this summer

- (last week I spoke more about it at ElixirConf EU, stay tuned for that recording)
Like it said, it’s been an ongoing project, definitely been keeping me busy I post pretty regularly about it in the Nerves Discord
