The FTDI Basic from TinySine is a compact programming module for the FTDI FT232RL chip. Its pinout is designed to be compatible with Arduino (and clones) 5V/3V cards. The module includes a DTR pin to automatically restart your Arduino when an update is imported, without having to perform the manipulation manually. The module also includes LEDs to verify that the data transmission to the Arduino is working.

The module also allows you to change the Bluetooth name and PIN code of the Bluetooth 5.0 Tinysine amplifier modules. A guide is available in the Downloads tab of this page to make these changes.
