 PlatformIO development platform for IoT modules manufactured by Tuya Inc.
 
 The main goal of this project is to provide a usable build environment for IoT developers. While also providing vendor SDKs as PlatformIO cores,
-the project focuses on developing working Arduino-compatible cores for supported platforms. The cores are inspired by Espressif's official core for ESP32,
-which should make it easier to port/run existing ESP apps on Tuya IoT (and 3-rd party) platforms.

-### Realtek Ameba
-
-The logic behind naming of Realtek chips and their series took me some time to figure out:
-
-- RTL8xxxA - Ameba1/Ameba Series
-- RTL8xxxB - AmebaZ Series
-- RTL8xxxC - AmebaZ2/ZII Series
-- RTL8xxxD - AmebaD Series
-
-As such, there are numerous CPUs with the same numbers but different series, which makes them require different code and SDKs.
-
-- [RTL8195AM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8195am)
-- RTL8710AF (found in amb1_arduino)
-- [RTL8711AM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8711am)
-- [RTL8710BN](https://www.realtek.com/en/products/communications-network-ics/item/rtl8710bn)
-- RTL8710BX (found in Tuya product pages)
-- RTL8710B? (found in amb1_sdk)
-- RTL8711B? (found in amb1_sdk)
-- [RTL8710CM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8710cm)
-- RTL8722CSM (found in ambd_arduino)
-- RTL8720DN (found in ambd_arduino)
-- [RTL8721DM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8721dm)
-- RTL8722DM (found in ambd_arduino)
-- and probably many more
-
-Different Ameba series are not compatible with each other. Apparently, there isn't an official public SDK for AmebaZ that can support C++ properly.
