E-Paper Badge is a Hint at Great Things to Come
Friend of Hackaday, Drew Fustini, came to our Breakfast at DEF CON meetup sporting a name badge of his own design. The E-Paper Badge uses a Teensy LC to drive a 2.15″ E-Paper display. The row of capacitive touch buttons to the left allow the image to be changed, and he just happened to have the Jolly Wrencher in the gallery of choices for this picture.
This badge gets me really excited for this year’s Open Hardware Summit which is at MIT on September 27th. This year’s badge is a collaborative effort between a group on Hackaday.io! It’s basically Drew’s badge on steroids, and he told me the experience of working with a team has been really positive. It seems each time the group hits a hard problem or a pile of work that needs to be done, someone on the team grabs it and runs with it. It’s a great example of both certified open hardware and team development.
OSH Park is producing electronic conference badges for the 2018 Open Hardware Summit. The hardware has been designed Alex Camilo, based on concepts from the ESP trINKet by Mike Rankin. The badge features an ESP32 microcontroller and a 2.13″ E-Paper display.
OSH Park shared project for the Rev 3 by Alex Camilo :
We expect this to be the final revision.
It is ordered on Super Swift today and should be validated next weekend. This will allow us to order the full quantity PCB panels in August 13th. Assembly is estimated to be 10 business days from the day when all components and PCBs are received.

And for those interested, here is a link to a gallery:
Terminal output on Rev 2 prototypes:
The Rev 2 prototypes have NodeMCU boards soldered on to the back to serve as a USB to serial adapter.
One of the Rev 2 prototype boards that Alex sent me has the default e-paper demo:
The other has MicroPython installed! 🙂

It’s a little ESP32 Board. Perfect for controlling or sensing stuff in the real world and sync it to the internet! Despite that it features the ESP32 WROVER Module. This means it got 4MB FLASH and 4MB RAM. That’s an absolute incredible amount of RAM. I honestly have no clue for what I will ever need 4MB in my embedded Projects.
Why did you make it?
I wanted a small ESP32 Board with the pSRAM and which works and doesn’t eat your whole time to get it working and find it’s issues and quirks.
I’ve used the CP2102 Serial converter because this is the one, which works the best way to program the ESP32. Even Espressif uses this serial converter on their own dev boards.
What makes it special?
It’s propably the smallest ESP32 Board with pSRAM. Despite the size it’s ideal for battery operation. It uses under 200uA in Deep Sleep mode!
thingSoC is an Open Source socket system for IoT development and has just launched a new Crowdy Supply campaign:
Build any IoT or Networked device you can imagine!
The thingSoC Grovey! platform gives you the freedom to choose from hundreds of existing sensors, actuators, and radios to quickly create new electronic systems, in plug together configurations that were not possible before. Easily mix together different CPUs, Radios, and Peripherals, like Servos, Motors, Relays, Sound and Lights, and then program them in your choice of Integrated Development Environments (IDE).
The thingSoC Grovey Series files are available on GitHub:
- TSOC_Teensy3x: Teensy3.x Adapter for the Grove System
- TSOC_GROVEY_ONE: Model “Uno” Arduino Clone for the Grove System
- TSOC_GROVEY_FOUR: Model “Four” PSoC4 mini for the Grove System
- TSOC_GROVEY_WIFI: ESP8266 Wi-Fi Adapter for the Grove System
- TSOC_GROVEY_I2CHUB: I2C Hub/Switch for the Grove System
- TSOC_GROVEY_GPIO: SX1509 GPIO for the Grove System
- TSOC_GROVEY_UART: USB to UART for the Grove System
This shield can be used with or without HydraBus board, you can even cut HydraBus specific right side (on the line) to have a tiny ESP-WROOM-32 breakout board.
hydrabus has shared the board on OSH Park:
Mike Rankin created this board with a tiny OLED display controlled by an ESP8266:
I created this design as a challenge to make a design under 1″ x 1″ in size.
The hardware is an ESP-01 ESP8266 Wifi module, linear power supply, microUSB connector and a few oled display parts.
The design files and source code are available on GitHub:
Here is a video of the assembly and operation:
miker has shared the board on OSH Park:
ESP32-WROOM-32 modules are in stock now! Again these are from the very first lot and with limited supply. To give chances to more developers to try them we will not allow more than 3 modules per order. This module is good only if you develop your own board. For these who are not good with […]
