 ## Electrical design
 
-The [most recent design](/PCB/KiCAD/HAN_ESP_TSS721) uses an [ESP8266](http://esp8266.net/) in an ESP12 module from [AI Thinker](https://www.ai-thinker.com) for micro processing and the [TSS721](http://www.ti.com/product/TSS721A) from Texas Instruments for level conversion from M-Bus to TTL (3.3V). An earlier design solved the level conversion using an op-amp, which might be an easier and more available solution, but also more error-prone. See more details in [electrical design](./Electrical).
