Excellent module. Works well. Highly recommended.
Bought 5pcs Pro Mini 328p 16MHz 5V, they arrived quick, including the 'combs' to solder myself. Good ESD packaging. However, they did not have a bootloader installed! I used an Arduino Uno and the Arduino IDE to upload the bootloader, after that they all worked good. BTW, they arrived in a combined shipping by AliExpress.
