R5 is only needed if U3 is populated.***PART | Value | Description----- | ----- | -------U1 | | Arduino Nano V3U2 | | Micro SD-Card Adapter (with onboard bidirectional level shifter)U2 |Pin strip| 1 Pcs 2.54mm Single Row Male Pin Header Strip For mounting and connecting Micro SD-Card Adapter directly into base PCB. Cut out one with 6 pins and two with single pins. The current angled pins on module will be desoldered and removed.U3 |PVG612S| Solid State Relay, 6-SMD (0,300", 7,62mm) Automatic power down with the Amiga (optional)J1 |DB25 | DB25 Male MountingHoles J2 |5.5x2.1 mm | Barrel Jack Power Connector, center positive (optional)C1 |100uF-220uF| 1210 ceramic decoupling capacitor for VIN, 16 VDC or at least above you voltage input 7-12V.
