+This repository hosts the documentation for `pax-devices` and related ESP-IDF
+components.
+
+Devices
+===============================================================================
+
+There is a gateway, ESP32 based devices and STM32 + RFM69 based devices.
+
+pax-Gateway
+-------------------------------------------------------------------------------
+
+The purpose of this gateway is to either:
+
+* connect a RFM69-based network to Wi-Fi using RFM69HCW and ESP32-WROOM
+* connect a LoRa\ |trade| transceiver to Wi-Fi using RFM95/96/97/98(W) and ESP32-WROOM
+
+The gateway was designed for power efficiency without sacrificing functionality.
+
+Devices based on ESP32
+-------------------------------------------------------------------------------
+
+**pax-DLED** is an ESP32 controller for digital LEDs. It is designed to support either:
+
+* two rows of WS2812, WS2812B, ... (*aka* NeoPixel) and derivatives like SK6812
+* APA102 (*aka* DotStar) and derivatives like SK9822
+
+**pax-DLEDGrid** is designed to use 64 WS2812* DLEDs like a single coloured LED.
+It stays in Access Point mode and is controlled through HTTP. The firmware is updated over-the-air.
+
+STM32
+-------------------------------------------------------------------------------
+
+* Light, Humidity and Temperature sensor powered by AAA batteries (*built,
+  not added yet, to be imported from PAx5 project*).
+* Light, Humidity and Temperature sensor powered by Li-Ion / Li-Polymer battery
+  charged by a solar panel (*almost built, not added yet, to be imported from
+  PAx5 project*).
+* Smart relay to control a heating system (*almost build, not added yet, to be
+  imported from PAx5 project*).
