The latest firmware and PCB is here:
besides from being smaller, there's now a regulator on the supply voltage:
Vs = 1.22 (1 + R₂/R₁) = 1.22V(1+ 2.7kΩ / 1.2kΩ) = 3.96V
The pinout has been changed:
and so has the GPIOs on the STM32F401re, so everything's much easier to connect:
(The CCD-PCB in the picture is a prototype)
As always go to https://tcd1304.wordpress.com to be sure to get the latest and greatest firmware and software, and instructions to match.
The PCB is available directly from http://dirtypcbs.com/store/designer/details/8475/5829/tcd1304-4v-zip
It's only the UART-firmware that has been updated. The SPI-version will follow shortly.
Both firmwares (SPI and UART) been updated with the new GPIO-configuration:
- fM on PB0
- SH on PA1
- ICG on PA0
- OS on PC0
