ESP32 Keyestudio Board with 3 LEDs Bluetooth Control :KS5020

The Keyestudio board called KS5020 has Bluetooth and WiFi. The key points are that this board is super cheap, has 3 pins (v,gnd and signal) per pin/out so that we can use Keyestudio and Elecfreaks peripherals which come with 3 pins and Keyestudio gives a very detailed tutorial system for using the board and peripherals. Elecfreaks also gives good instructions for their hardware usage. Also, the KS5020 can connect to WiFi and upload data to the cloud so we can use it for smart home, smart farming and smart science projects; with ThingSpeak. You will find Keyestudio kits for these smart projects with different KSxxxx numbers but they use this board: KS5020 and it is similar to boards made for smart projects for Microsoft MakeCode and the BBC Micro:bit so we can carry on from that level to higher level text coding in Arduino.
