New PCB design for a new potential job demo.

(Two Way Radio SELCAL / 5 TONE / SEQUENTIAL TONE decoding and encoding)

Using a STM32F405 for its floating point (using DSP for this application)

In this case we are using a Waveshare CORE405R PCB (I can’t buy the parts that cheap, and their board already has the basic support ready to go, big time saver for a demo)

includes support for

• micro SD card socket
• USB host socket
• D25 for IO for the demo (RS485, 2 analog inputs, 2 analog outputs, 2 open collectors / drains, power supply)
• expansion IDC (for anything else later)
• 320 x 240 TFT lcd (ZEAL 2.2″ TFT module) (under the PCB)
• IIC user switch and leds next to the TFT (under the PCB)

I have ordered 10 boards, only using 3 so far

Will exchange a board (just the pcb – no parts) for a coffee if you are in the Sydney area
