Customer Comments

  • i just noticed is the only way to provide power through the headers EXT2 and JTAG Header? Kinda sux but still a great price. Ill just make a nice wiggler clone that will provide 5v since most all ARM is 3.3v and have a regulator on board.
    Love the site btw!

  • I was worried about the crystal thanks for asking! Ima order this today!

  • Is the crystal in a removeable socket?

    • Yes, it is. Well, only the crystal is removable; the socket is soldered to the board. ;-)
      It’s the usual HC49/U or HC49/US thru-hole form-factor.
