Pro Mini ATMega328P 3.3V 8MHz

Clone of the Arduino Pro Mini with ATMega328P microcontroller operating at 3.3V 8MHz. 100% compatible.
The Pro Mini was designed as a low cost microcontroller board which can be left embedded in your design.
On-board voltage regulator allows supply voltages between 3.3V and 12V.
There is no USB interface so programming is via a stand alone programmer, such as the USBasp, a Uno board or USB-TTL FTDI adaptor.
Supplied with straight and right angled header pins for soldering to the board if required.
Wiring the Pro Mini to a USBasp is shown here.
