Espruino Pico Adaptor PCBs

Great - it's a per-board setting in Eagle, and I think sometimes I forgot to tweak it.

I'm still really interested in an 'uber-shim' with snap-out parts for common devices. I wonder what the most common/useful ones would be?

• HC-05/HM-10 bluetooth (maybe on end of board)
  
• ESP8266 - ESP-01 and ESP-12
  
• Micro SD card (on end of board again)
  
• WIZnet ethernet (tweaked to put the Pico on the opposite side)
  
• MAX1551 LiPo charger IC
  
• Arduino (could add too much to the cost though)
  
• FETs or ULN2003 IC - for high current drive
  
• NRF24 (I wonder how many people are using this now?)
