Tellur TLL331241 IR Blaster comes with the WR3E module, it can be easily changed to ESP12S (1:1 pin compatible). Just flash
tasmota-ir to the ESP12S and change it.
The pinouts are IRrecv=GPIO5, IRsend=GPIO4. The device also has a AHT10 temp/humid. sensor which is connected to a MCU. However it can be directly soldered to the ESP (on 2 free GPIOs) and used without problems (via I2C, requires custom build with ATH10x support). For this the legs 7+8 (counted from top of right side) of the MCU which are connected to the AHT10 have to be cut (see picture).
