 ### Hardware notes
 
-* For low-power transmitters, a `Pro Mini 3V3 8MHz` bare board with ATMega328 microcontroller is highly recommended. The board has no serial interface chip which reduces continuous power consumption. An external FTDI232 - USB serial interface should be connected for serial console / programming. (See red PCB on the picture)

+* ESP8266
+* ESP32

  The SMD power LED should be desoldered from the Pro Mini to reduce continuous power consumption. 
-* A transmitter with (protected) 1500mA 18650 battery can operate for at least 6 months with `LowPower.h` functionality implemented. (By sending the temperature every 30 seconds)
-* Changing the BOD (Brown Out Detection) fuse to 1.8V allows operation between 1.8 and 4.2V 18650 battery. (Explanation beyond the scope of this project)

 * 1 to 3 temperature transmitters are supported, similar to the original Oregon THN128 temperature transmitters.
-* Check [list of counterfeit DS18B20 chips](https://github.com/cpetrich/counterfeit_DS18B20) , because this makes a huge difference in accuracy and read errors at 3.3V. Many DS18B20 chips from Aliexpress are counterfeit and won't work reliable at voltages below 3.3V.
-* [NiceRF Wireless Technology Co., Ltd.](https://nl.aliexpress.com/store/934254) sells high quality 433MHz transmit (STX802) and receiver modules (STX882) with a good range.
