Please, consider that this sale is for a bare AlphaBrd PCB without any components or pin headers. If you would like a kit with the components, please contact me. The AlphaBrd operates from a single 8V - 12V DC power supply. It provides 3.3V and 5V to other devices by means of two AMS1117 LDO linear regulators. For voltage level translation, it uses one 74(A)HCT245 and one 74LVC245 integrated circuit. An led indicates if the board is powered. There is also a protection diode in case you accidentally reverse the input voltage. The AlphaBrd performed very well in my tests spanning several months.  I designed it using the latest stable version of the open-source EDA software KiCad. The boards are manufactured locally in Bulgaria (EU) and have an ENIG (Nickel/Gold) lead-free finish. In the last but one attached picture, you can see a test of the internal temperature sensor of the ATtiny mounted on our custom BetaBrd. The BetaBrd is running at 3.3V on its internal RC oscillator. The AlphaBrd power supply and voltage level translator board (on the right side of the picture) is used to generate the main voltage. The AlphaBrd also powers and interfaces with the character LCD display which operates at 5V. In the last attached picture, you can see the KiCad schematic of the prototype of the AlphaBrd. More information about the board can be found at: http://www.ilchev.net/alphabrd As always, this is a private auction without any guarantees.
