MicroUSB powered ESP8266 Oled Board

logo.jpgMike Rankin created this board with a tiny OLED display controlled by an ESP8266:

MicroUSB powered ESP8266 OLED Board

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:

I’ve been keeping an eye on the SSD1331 library to see if it would eventually work with the ESP8266 wifi modules. I noticed the support for it appeared one day with the Adafruit library so I tried it out on my Adafruit Hazzah and success!

SAMD21 giveaway — 0miker0’s Blog

What I’d like to give away one SAMD21 logger/sensor board to someone, wherever in the world you are. Why I’m a hardware guy, not a programmer. I’ve had fun designing this project and wrote simple code to verifying everything works. There is enough hardware and sketch space available to create a pretty cool logger project. […]

Atmel SAMD21G Sensor Board

Mike Rankin created this tiny sensor board with an ARM Cortex M0+ microcontroller and OLED display:

0miker0’s Blog: SAMD21G Sensor Board

It’s pretty tiny so a 4 layer board made the whole job easier. The top and bottom are pretty much dedicated for components, layer1 are tracks and power traces, layer2 is a ground plane. Mixing up an internal plane and routing layer was interesting.

Screenshot from 2016-09-21 09-43-22.png

The hardware consists of:

  • SAMD21G18A processor (used in the Adafruit Feather)
  • HDC1080DMBT temperature/humidity sensor
  • ADXL345B accelerometer
  • DS1340U RTC
  • MCP73833 LiPo battery charger
  • MicroSD card connector
  • Navigation Button and pushbutton
  • 0.66″ mono oled display
  • Micro USB connector for charging and uploading new sketches
