Tech Specs

Hardware:


An Avoccado° device contains one mainboard. Each mainboard contains the following hardware:

  • Nordic Semiconductor nRF24L01+ wireless radio
  • InvenSense MPU-6050 gyroscope and accelerometer
  • Atmel ATmega328P micro controller
  • A voltage regulator with ultra low quiescent current

Some versions of the Avoccado° boards have additional features:

  • Low impedance output for loads, paired with a vibration motor output for haptic feedback
  • Capacitive touch sensing
  • 1sXp rechargeable battery (for example upcycled 18650 cells from dead laptop batteries where individual cells are still okay)
  • LiPo/LiIo charging IC like the Maxim MAX1555 to recharge the onboard battery via USB, a Qi receiver for wireless charging, or a Texas Instruments BQ51050B Qi compliant integrated secondary-side LiPo charger which combines the both

Software:


All parts of Avoccado° are Open Source and the code will always be available as FLOSS – free, libre and Open Source software. Feel free to participate and push the development.

 

A typical Avoccado° node is about 24 x 24 mm² small. It can use movement as an input and give haptic feedback with vibrations.

An Avoccado° prototype with a CNC milled enclosure out of oak wood. For debugging purposes and flashing new firmwares it's connected to a laptop via USB. It can easily be reconfigured with the Arduino software or just flashed with avrdude if you are more advanced. In normal operation Avoccado° does not need any cables or external energy sources.
