Seeeduino - ideal for model railway animations?

[Stephen Rainsbury]

I was not aware of the "Seeeduino"  which is described as
Features
ARM® Cortex®-M0+ 32bit 48MHz microcontroller (SAMD21G18) with 256KB Flash, 32KB SRAM
Compatible with Arduino IDE
Breadboard-friendly
Small size: As small as a thumb (20x17.5mm) for wearable devices and small projects.
11 x digital/analog pins
10 x PWM Pins
1 x DAC output
1 x SWD Bonding pad interface
1 x I2C interface
1 x UART interface
1 x SPI interface



At under £5 each this would seem to be ideal for animations, point motor controllers and lighting rolling stock etc, or am I missing something?

Seeed or Seeed Studio does appear to be an established Arduino clone and other device producer with a decent reputation.

There seem to be a lot SAM M0+ (or similar) Arduino compatible boards available. How one decides which one to go for I don't know. Seems a good price though and the DIP-like packaging looks good for mounting on PCBs.

OK, gobbledygook over.  ;D

That looks very interesting Stephen, thanks for the info.
