This is an amazingly designed little piece of technology. I will definitely be purchasing more. Elegantly constructed, and great functionality. Gordon is brilliant, and has done a great job implementing ecmaScript on hardware this way; truly inspiring.

The only snag has been the unfortunate conflict when broadcasting advertisements that it blocks the process for being able to connect and edit the code for the unit -- but this is a natural outcome of the circumstances involved. I do believe it can be improved, but users should be aware of the potential stumbling block.

can be used as a 0.05 to 0.1 breakout

For Espruino Pico WIZnet W550io Ethernet Shim

I thought I should leave a review here because the shim worked for what I bought it for, even though that wasn't it's intended purpose. Just cut the long parts off using a small pair of side-cutters. Then place the shim between the plastic of the header pins and the Pico itself, then solder the headers as normally installed on the Pico. This allows you to add 8 more 100 mil (0.10") header pins face up for use with a breadboard and male to female prototyping wires. And now you can make use of those tiny pins that looked unusable previously.

Must have for JavaScript lovers!

For Espruino Pico (pinned)

Not that I "hate" C and it's successors, it's just that I am lazy and I hate the extra work that goes into those frameworks. So I guess I hate them.
Especially as a web developer that prefers node, I feel right at home programming things with JavaScript which leads to a lot more fun with the project and a lot less debugging. Not to mention I can now steal straight from my existing code bases!
Winning!

Lowest TTFHW ever

For Espruino Pico (cosmetic damage)

I established my new TTFHW (Time To First Hello World) personal record: 30 seconds. Forget Arduino, this cutie is way more powerful and easy to use.
Shipment perfectly in time.

Smallest js computer

For Espruino Pico (cosmetic damage)

I am impessed by the size and seamless working with the espruino ide. Will inspire me on my way to js mastery.

Great little board for your next IOT project :)

For Espruino Pico (cosmetic damage)

Got a little damaged during shipping (it seems someone at royal mail decided to leave my package at the bottom of the stack and load a ton of bricks on top it so the pins were bent. No problem bending them back straight tho). (Raelly there must have been a ton of bricks on top as the packaging was pretty good).

Getting the lights blinking took about 2 minutes (if you are on linux remember to give yourself access to the serial port ;)

Now I just need the next killer IOT idea (and maybe the wifi module and the shim for it.. and the battery.. and lots of other cool toys ;)

Awesome product and very kind communication

For Espruino Pico (cosmetic damage)

Just received my Picos and try them out.
>> I never had such an awesome microcontroller.
Do everything you want with Javascript out of the box!!!

The contact with Gordon was also very kind.
I really recommend these little cute Espruino Pico boards!
Go and buy some!!!

Hopefully my ESP8266-01 modules will arrive this week, then I go to add WiFi to the Picos *wooohoo

btw. Shipping to Germany was fast and well packed.

Thx Gordon for mailing me and for the shims ;)
