I2C-7313-cTc Version 2.2
First built: 2017.11
- 1.x - See the [I2C-8574-cTc](/pages/I2C-8574-cTc.html) versions, which are simple wiring-to-I2C adapters.
- 2.1 - Initial version
- 2.1-panel - manual panelization
- 2.2 - Manual panelization of the 2.1 design, made such that the unbroken board set would exactly fit the 2” spacing on the cTc machine panel.
