cp2102 ttl to usb shield
Designed and created USB to TTL shield using cp2102 chip that has nearly the size of PinSocket_1x06_P2.54mm_Horizontal shield. So that either PinSocket can be soldered or when permanent micro USB is needed this little board.
1st version
Pictures of first working/tested version below, KiCAD files on GitHub.
It nearly worked out of the box, but for the RX&TX transmit led indication. Those needed to be enabled (cp2102 programmed) using Simplicity Studio 4 and Xpress configurator. It's all well described in AN721: USBXpress™ Device Configuration and Programming Guide.
