Powered by the G2C1 controller, this general purpose module is small enough to easily fit in space-constrained applications. It runs on 5V, either directly or via a USB connection. It has a wealth of I/O interfaces for connecting to other sections of a medical or industrial product.
* Other hardware options are available, see Custom Modules.

Power and Grounding
The G2C1 module requires a 5V DC input, +/- 5%, on jumper J3. At boot-up it uses a maximum 650 mA with no external devices attached. If the module will be supplying power to external USB devices (500mA max.), the input power should be a minimum of 5.15 V to meet the USB specification at the far end of the longest USB cable run. The module can also supply +5V to other external devices on some of the connectors, and all such supplies need to be considered in the power budget. The input power connector can handle 3A of nominal 5V input. The module can also be powered via the USB OTG connector. Please consult Reach for requirements to power this way.
The board mounting holes are connected to a digital ground. These must be connected to a chassis ground either directly or through a transient protection diode for ESD. The resistive touch circuit has ESD protection that shorts ESD on the touch panel to the board mounting holes.

Detailed Explanation: On orderly shutdown, Linux was writing the last known time to /etc/timestamp, and then on power-on, it compared the time from HW real-time clock with the file value and set system time to the “lastest” of the two. The problem is, if the HW clock battery dies, the “later” time is invalid but might only be off by an hour or a day and not enough to draw attention, but if the application is doing time/date data logging this could be enough to mess things up. By making it rely on the HW clock only, if the date is wrong it will be 1970 which should be obviously wrong.
Consider getting a microSD card extension cable if you are doing a lot of development and frequently replacing the microSD card in your module.
Other accessories come with Development Kits. However, some customers need additional items for prototyping. In that case, items can be purchased online by model.
