content: Please refer to the following thread for more details and discussion about this device:https://www.eevblog.com/forum/projects/diy-milliohmvolt-meter-kit/I now have a limited number of these kits in stock. Each kit is priced at$62(shipped worldwide with tracking) and comes with the following:1. PCB.2. All the components except the optional external voltage reference (REF5025)*.3. A programmer to program the MCU.4. A pair of basic (i.e. not very high quality) Kelvin clips, wires and banana plugs. Will require assembly.5. Acrylic case, banana sockets and button caps**.6. Documentation in English including the part list, schematics and DIY guide.7. Latest version of the firmware and the source code.* The external voltage reference (REF5025) is an optional item. The device "dual boots" into 2 different modes at startup, Voltage Meter or MilliOhm Meter, and this reference is only used in the Voltage Meter mode. The device will work fine without it, as there's a built-in reference in the MCU already. The chip will cost an extra$2.5if you want to include it.** In the other forum thread I posted pictures of the unit I assembled myself. Mine has red buttons. However, the kits I received from the author have buttons of different colours. I have made sure each set has uniformly coloured buttons but they may be either red, white, or yellow. I'll try to accommodate it if you have a particular preference, otherwise I will randomly pick a colour for you.EDIT:The LiPo battery isNOTincluded. You will need to find yourself an old mobile phone's battery or something similar. It can be powered by USB too without a battery.Please PM me your Paypal email address if interested. Thanks for looking!Cheers,Franky

content: Any details of the programmer? Is it possible to get a kit without a programmer?

content: Quote from: krivx on May 19, 2014, 01:49:23 pmI don't really have detailed information about the programmer. I'm attaching a picture of the device (sorry about the poor quality, don't have a good setup at home).The main chip is a C8051F320. It comes with the kit I sell, I'm afraid I can't sell one without it, sorry.

content: Quote from: iloveelectronics on May 19, 2014, 02:45:28 pmJust wanted to add that, as Jaxbird pointed out in the other thread, it is not recommended that one attempts to put this kit together if he/she hasn't had any SMD soldering experience before. It's not awfully difficult though as I myself had minimal SMD experience and still managed to get one to work
