Introduction
Introduction
ANAVI Infrared pHAT is an open source hardware Raspberry Pi add-on board with IR receiver, transmitter, UART and 3 I2C slots for sensors. ANAVI Infrared pHAT was
started as a hobby project by Leon Anavi in January 2017. The project allows you to convert your Raspberry Pi into a smart remote control using the open source
software LIRC.
ANAVI Infrared pHAT is designed with the free and open source electronics design automation suite KiCAD. No soldering is required. You can assemble ANAVI
Infrared pHAT to your Raspberry Pi with your bare hands.
Anavi is fully compatible with the Raspbian GNU/Linux distribution and open source sample applications are provided.

A proper config file for lircd is maybe the most vital part of this package, so you should invest some time to create a working config file.

To function properly, I2C requires a pullup resistor on each of those lines therefore ANAVI Infrared pHAT includes two 4.7kohm resistors labelled as R6 and R7. If for one reason or another you need to disable the I2C pullup resistors remove R6 and...
