In case you have trouble ordering, you may order a kit directly from my blog at
USPS has doubled international rates to around $12.75 to most part of the world. My blog sales page has more accurate rates.

Due to USPS mailing restrictions, a coin battery is no longer included in the kit. Sorry for the inconvenience.

You can also order a Phi-2 shield with 20X4 display here:
