WM2000EV

The WM2000EV is an evaluation kit designed for evaluating the capabilities of the WM2000 Programmable Wireless IIoT Module. One module is included in the kit and is preloaded with a demonstration app — the first chapter of our guided journey of exploration for the WM2000. Also included in the kit are a USB Type-C-to-A cable, a CR2032 button cell battery, and four jumpers installed in their default positions.

The WM2000EV was designed to be completely self-contained and enable the exploration of the module's features without the need to wire in any external circuitry. It is equipped with all essential buttons and status LEDs, integrated light and temperature sensors, an RGB LED controlled by three I/O lines with pulse-width modulation (PWM) output, a backup battery, and the circuitry necessary for enabling the WM2000's low-power "sleep" mode.

The module is connected and secured to the WM2000EV through a unique lock-and-release mechanism consisting of two rows of horizontal spring-loaded pins. This mechanism allows for the effortless removal and insertion of the module and ensures reliable connections to its pins. Two 12x2 male pin headers are integrated into the board to facilitate the connection of external components.

The kit is powered either through a two-pin terminal block for 3V-5.5V input or via the USB Type-C connector, which also allows for the serial debugging of the WM2000.

The jumpers toggle the power source for the module's real-time clock and enable or disable the low-power mode, as well as allow for measuring current consumption of the board and/or module.

In addition to hosting all the primary hardware, the WM2000EV's front plate features quick-response (QR) codes linking to CODY, Tibbo's project code wizard, and the L.U.I.S. (Loadable User Interface System) web app. The backplate has "unboxing" instructions and a QR code linking to the Getting Started guide.
