It recently occurred to me that I have been accumulating microcontroller development boards for a while, so I thought I'd lay them out for a photo!

Reading left to right, top to bottom you can see:

• STM32 value line Discovery board
• STM32-L Discovery board
• STM32-F0 Discovery board
• STM32-F4 Discovery Board
• Cubieboard
• Freescale Freedom KL05Z
• Freescale Freedom KL25Z
• Freescale Freedom K20D50M
• Raspberry Pi Model A
• Raspberry Pi Model B

• Digistump Digispark, with and without headers

• Xino Arduino kit, not yet assembled

• Genuine Arduino Uno R3
• Arduino Uno clone from SainSmart
• Gainer PSOC
• Propeller

The trouble is I keep spotting new ones and being tempted to buy them too!
