TransistorTester-ProMini - UNTESTED (fixed)
author: kronenpj
2 layer board of 2.02 x 1.07 inches (51.3 x 27.3 mm)

$10.80
UNTESTED - Under development
This is an adaptation of TransistorTester to use the Arduino Pro Mini. Inspired and heavily influenced by Stefan Wagner’s implementation. This is the reason the resistor numbering starts at R3, for instance.
This version (1.4) fixes two numbering / pin assignment errors from the previous version. This also increases the size of the vias in the display connector and several other minor tweaks.
Bill of materials:
- 1x U1 - Arduino Pro Mini
- 1x U2 - 2.5v Precision Voltage Reference, LM4040DBZ-2.5, SMD SOT-23-3 footprint, Optional
- 1x U3 - I2C 0.96" OLED Display
- 1x J1 - 6-pin Female, 2.54mm Header Socket
- 1x J2 - USB Micro-B, Molex_47346-0001 (Used for power only)
- 1x J3 - 6-pin Male, 2x3, 2.54mm Header, Optional (ICSP interface)
- 1x SW1 - Push Button Switch 6mm (SW1), or 12mm (SW2)
- 1x R3 - 27k Ohm resistor, SMD 0603 (1608 metric) footprint
- 1x R10 - 2.2k Ohm resistor, SMD 0603 (1608 metric) footprint
- 3x R4, R6, R8 - 680 Ohm resistor, SMD 0603 (1608 metric) footprint, use 1% or better precision
- 3x R5, R7, R9 - 470k Ohm resistor, SMD 0603 (1608 metric) footprint, use 1% or better precision
