New PCB: 12% smaller, 12% cuter, 24% easier

A project log for Linear CCD module

TCD1304-based linear CCD module driven by a Nucleo F401RE or an STM32F103 blue pill

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 (slightly improved compared to the one in these images) is available directly from http://dirtypcbs.com/store/designer/details/8475/6065/tcd1304-4vn-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:
