Introduction This design guide is intended to provide a good understanding of the functionality of the OEM200 module. The intended audience is the engineer responsible for integrating the OEM200 into a product. Description and Specifications The OEM200 is a component of the Sensicast A2400 Wireless Sensor Network Platform – a completely selfconfiguring, self-healing, power managed sensor network.
Optional temperature and humidity sensor The OEM200 can be preloaded with a temperature and humidity sensor at U7. Please contact Sensicast for temperature and humidity specifications. Connectors The primary interconnection is J1, the 41 position board-to-board, header (Hirose p/n DF9A-41P-1V(20); mates with: Hirose p/n DF9A-41S-1V(20)) on the bottom of the assembly. (Please note that this header is common between the OEM200 and OEM100).

Functional descriptions Power: The module is powered by a DC power source from 2.0V to 3.3V. The absolute maximum voltage that should be applied is 3.6V. VCC and VSUPPLY are connected through a 0Ω resistor on the module. The power plane is attached directly to VCC. J1 can carry 100mA per pin; J3 can carry 500mA per pin. Ground: These are attached to the ground plane of the module. J1 can carry 100mA per pin; J3 can carry 500mA per pin.
Mechanical interface (all dimensions in inches unless otherwise noted) Top side module height: max 0.255” Bottom side module height: max 0.149” The OEM200 is a printed circuit board (PCB) assembly with two connectors (J1 and J3) and three mounting holes. The primary interconnection is J1, the 41 position board to board, connector on the bottom of the assembly. When loaded into its mating connector on a carrier board, the bottom of the OEM100’s PCB will be 4.3mm (0.
Recommended Carrier PCB Layout 0.216 landing area x3 0.104 through hole x3 1.38 0.99 The OEM200 occupies 1.60” by 1.58” and is designed to plug into a PCB mounted, 41 position, Hirose DF9 receptacle (Hirose p/n DF9A-41S-1V(20)). Please refer to Hirose’s documentation for more information about this connector. There are three mounting holes designed to accommodate 4mm plastic stacking posts (Richco p/n MDLSP1-04M-01).
Technical Specifications Radio frequency Radio power Battery life Range Connector options Antenna LEDs 2.
Appendix A Developer’s Kit Adapter Board Optionally a Sensicast Developer’s Kit Adapter Board (P/N 1408) can be used to ease prototyping with the OEM100/200. There are .104” diameter mounting holes that correspond to the mounting holes of the OEM100/200. The board has a Hirose receptacle that mates with the OEM100’s 41 position header. Each signal is brought to a test point arranged on a 2mm grid.
