Arduino and GMLab products
GMLab products are smart devices built and concieved by the same team behind Crumar and GSi products.
Most of them are based on Arduino platform and totally (or partially) open source. The concept behind these products is to offer these products with a low cost (also sold in DIY KIT) and highly customizable features. This means that we offer source codes, design files to everyone (via github) even if the products are pre-programmed with a "factory" firmware with the basic and factory-defined features of the instrument.
The source code is based on Arduino, the easy and famous hardware and programming platform: this makes the units customizable by the customer (this requires programming and coding skills). We offer support on the product only with the stock firmware installed.
PLEASE NOTE: WE DO NOT OFFER SUPPORT ON REPROGRAMMING THE UNITS, HOW TO INSTALL AND USE THE ARDUINO IDE AND WE CAN'T HELP CUSTOMERS ON THIS PROCESS.
But you are not alone! The Arduino community is very big and helpful.
