The circuit and PCB have been produced and tested and basic code is available on github. See the project site on hackaday.io for more information about the project.
# Simple yet powerfull!
This board provides solid connection between Wemos D1 mini (ESP8266) and 2.4" TFT ILI9341 XPT2046 SPI Display (TJCTM24024-SPI). The main goal is to build cheap wi-fi enabled display with touch interface for use in various IoT projects. Display communicates with ESP8266 via SPI (di...

Home air monitor is based on the development board NodeMCU (CP2102 version). It includes a temperature sensor - ds18b20, a humidity sensor - HTU21D, a carbon dioxide sensor MNH-Z19. It is also possible to connect one more i2c sensor and a radio module to 433 MHz.
A ESP-12 IoT controller for RGB LED Stripe 5-12V.
3+1 channels through MOSFET, PWM and dimming functionality.
The MOSFETs can be replaced by NPN Power transistors (input resistors are as THT parts placed, the 10k pull down's not needed.
The 4th channel is a Logic level up-converter (3.3V->5V). Driven by a 2N7002, can be replaced with BSS138 or similar. Note that it's is a very small power output...
