CW308T-XMEGA
The CW308T-XMEGA fits an Atmel XMEGA device.
I/O Connections
| CW308 Pin | ATMega328P Pin | Notes |
|---|---|---|
| GPIO1 | PD0 (RXD) | Serial INPUT to AVR. |
| GPIO2 | PD1 (TXD) | Serial OUTPUT from AVR. |
| GPIO3 | N/C | |
| GPIO4 | PC0 | Trigger pin (mapped to ADC-port such that I/O driver power comes from AVCC). |
| CLKIN | XTAL1 | |
| CLKFB | PB0 | Can set this pin as CLKO with fuse. Useful for synchronizing to internal RC oscillator. |
| nRST | nRST (PC6) | Used by in-system-programming (ISP) interface. |
| MOSI | PB3 (MOSI) | Used by in-system-programming (ISP) interface. |
| MISO | PB4 (MISO) | Used by in-system-programming (ISP) interface. |
| SCK | PB5 (SCK) | Used by in-system-programming (ISP) interface. |
Programming Header
The 6-pin programming heading can be used with the Atmel PDI interface. The pinout of the 6-pin programming header on the main-board allows it to work with standard Atmel ISP tools:
