STEVAL-SPML9; STEVAL-SPML868 USB dongle for SPIRIT low power RF modules SPML-868 and SPML-9 Data brief Features Based on SPIRIT sub GHz modules SPML-868 and SPML-9 USB interface and power supply RESET button On-board antenna RoHS compliant Description The STEVAL-SPML868 and STEVAL- SPML9 boards are design tools that allow evaluation of ST's SPML-868 and SPML-9 low power RF modules in a quick and simple way. The dongle includes the module to evaluate, an on-board RF antenna, and a USB connector. The USB connector is used to connect the dongle to a PC, to access the sub GHz RF module and to supply the dongle. The STEVAL-SPML868 and STEVAL- SPML9 downloaded firmware enables the user to create a SPIRIT link using simple AT commands. The SPML-based dongle is not qualified. It is a demonstration tool only, to be used strictly for evaluation purposes. It is not a product in itself.

I/O Connections STEVAL-SPML9; STEVAL-SPML868 I/O Connections. Pad references In addition to the USB plug, several pads are also available. Pads to (indicated by the yellow boxes in the figure below) render the SPML-868 / SPML-9 module pins available to the user. There are also six jumpers (indicated by red boxes) for current absorption purposes and for reprogramming the module firmware. Figure : Available pads and jumpers Table provides a description of the pad connections. /9 DocID078 Rev
