Espruino PCB's produced by Ragworm UK.
Ordered these little beauties when the exciting Espruino Kickstarter project finished and the whole system (Software, Firmware and Hardware) all went open source so people can follow along during the Beta testing of the project before the final populated boards produced by Seeed are released sometime in December-February once the team are happy with the design and ironed out all the bugs.
I am a big fan of the ARM Cortex-M3 and already own 3 different STM32 based boards that are supported by Espruino (to some extent), I felt like to get the best experience out of this fantastic concept was to have a set of boards printed, stock up on components and build and test each revision of the board until the final production model is released.
Its an exciting prospect of having a Java based ARM-Cortex dev board out there as it pairs two very powerful but easy to use systems together.
I dont doubt that we will see other makers follow suit with this kind of board over the coming year as its a great idea.
Ragworm.eu have the design and have done (as usual) an awesome job producing the PCB's in their beautiful Orange! If you would like to get involved then please head over to the official Espruino website and sign up for information, download the tools and code that is available. The PCB files are available on their official site as open source but if you want to have an orange one (or more) made to build yourself then give me a shout and I will point you in the direction to be able to order the PCB's from Ragworm UK and give you the Bill of Materials and Component values.
(Please bear in mind that these boards are designed for a pick and place machine and re-flow soldering. They CAN be done at home if you have something you can use to re-flow solder the 64 pin MCU, USB and SD card slot (hotplate, hacked toaster oven, Hotair Re-flow station etc..) and the rest can be done with an SMD tip on your soldering iron (The Antex XS25 with a #57 0.12mm Copper tip is my weapon of choice and a great combo for small SMD work) and you will also need some magnification (a 4x magnifing unit is ideal but you could just get away with a 2x if your sight is 20/20).
Its doable but is not recommended unless you are very competent with SMD soldering or know someone with a P&P machine and re-flow gear.
Espruino was created by Gordon Williams and all Espruino Hardware and Code is of his design and released under general Open Source guidelines. You can find out all about Espruino here : www.espruino.com/
This is NOT my design and I am not affiliated with Espruino. I am just a big fan of the project and want to help iron the bugs out of Beta models to aid the final production release time to be as fast as possible (Trust me I wouldn't hand solder a board covered in 0603 components and a 64pin MCU by choice (All the Beta tester slots were taken).
