Total Price: $6.25

This board adapts the GPSDO diagnostic port to USB. You get to select whether to transmit the diagnostic output or the GPS NMEA output. PPS is sent to DCD, and is positive-oriented (that is, DCD asserts on-time). The USB interface is a CDC device. Open it and set it for 9600 baud 8N1.

The SSOP chip is a CY7C65213. The SOT23-5 chip is a single inverter. The USB connector is a microB one. The diagnostic connector is a CUI MD60S. The passives:

  • R1 - 10kΩ
  • R2 - 4.7kΩ
  • R3 - 1MΩ
  • C1, C2 - 0.1µF
  • C3 - 1µF
  • C4 - 2.2µF
  • C6 - 4700pF
