A USB2.0 compliant MINI-B type connector (UX60A-MB-5ST: Hirose Electric Co., Ltd.) is used.
For clock supply to the target device, a 14-pin DIP socket is implemented as CLK1. A 14-pin type oscillator (5 V)
A parts board such as the 160-90-314 (manufactured by PRECI-DIP) can be used with this socket to configure
Caution Be sure to turn off the QB-78K0MINI’s power supply before mounting or removing a clock in the
