This target used to come with many of NewAE’s starter kits, but has been replaced with the CW308T-STM32F3.
I/O Connections#
NOTE: The serial pins for this target are swapped compared to the usual setup. An example setup script can be found here: newaetech/chipwhisperer-jupyter
The pinout of this module matches the “NOTDuino” kit along with the “CW301 Multi-Target Board” routing. The following is the connection between GPIO1-4 and the I/O lines on the AVR:

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 ISP interface. The pinout of the 6-pin programming header on the main-board allows it to work with standard Atmel ISP tools:
