I got the 433MHz version. The T-Deer is advertized as an Arduino Pro Mini but it is an Arduino Mini. So, set the correct board in the Arduino IDE otherwise you will have problems programming it. It works very well. I use it to send RTTY and LoRa. What I did notice is that you will need to have some luck with the internal crystal as that is not temperature controlled. So frequency may deviate when it heats up when you have a bad crystal. Otherwise very good product for a reasonable price.

Tested, works well. Only board should be chosen in IDE as "Arduino Mini", not as "Pro Mini".

OLED display doesn’t work at all! It seems to be defective. Also I2C-Scanner doesn’t show any device at GPIO 21 and 22! Please send new! Greetings Peter.Fuellhase@hgt.de
