1 Description SPSGPE is a hardware LGA-SMT module for easy development of high performance wireless network applications for a wide range of applications. Compact-sized, low power and fully integrated, SPSGPE is available in 3 versions: SPSGPE-433 operating on ETSI 433 MHz band SPSGPE-868 operating on ETSI 868 MHz band SPSGPE-915 operating FCC 915 MHz band. All versions have the same pin-out and mechanical shape.

3 Hardware design 3.1 Pin usage If used with default firmware and interfaced to a host microcontroller unit, SPSGPE requires minimum power, ground and UART to transmit and receive signals, that is to be connected. Other signals are optional and provide additional functionality. Unused signals must be left unconnected. In case the module is connected to a host microcontroller unit, SPSGPE pins requiring connections are outlined in Table 9.
3.2 Typical application circuits In a typical application circuit, SPSGPE is connected to a host microcontroller unit through a standard UART to transmit and receive signals. This application is pictured in Figure 2. Figure 2. Typical application circuit of SPSGPE connected to a host microcontroller. Please notice that “USB / RTS” could be left floating if USB is supported by firmware. In another typical application circuit, SPSGPE is connected to a host computer through a standard USB connector.
NOTE: when using the SPSGPE in a USB self-powered application, USB back-voltage test requirement must be met (i.e. a maximum of 400 mV may be measured on the VBUS, D+, or D- when the device is not plugged into a USB port). For this purposes, SPSGPE requires to receive on the pin USB_DEV_CONN a signal indicating, when set at high logical level, that the VBUS is detected in order to properly control the internal pull-up resistor connected to D+ line available internally to the STM32L151RDY6.
Special features are enabled by the following pins: - STAT_LED (pin TP10): output to drive an external LED and indicated status of SPSGPE connections. If this pin is used as output to an external LED, possible outputs are listed in Table 11. LED Output Periodic single flashing with long ON time and short OFF time. Periodic single flashing with short ON time and long OFF time. Description Application is waiting for commands from DTE. Periodic fast double flashing.
3.3 Layout guidelines When adopting SPSGPE, please consider the following guidelines for a correct PCB design: 1. A minimum four-layer PCB is suggested. 2. At least one of the PCB layers should be used to implement a copper ground plane without cuts. 3. Copper planes and/or heavy traces are recommended to implement power supply connections. 4. Decoupling capacitors (recommended values are 100 nF and 10 µF in parallel) have to be placed very close to power supply pins. 5.

3.5 Module reflow installation SPSGPE is a surface mount module supplied on a 46-pin, 6-layer PCB, with gold surface finish. Final assembly recommended reflow profile is outlined below, based on IPC/JEDEC JSTD-020C, July 2004 recommendations. Profile feature Average ramp-up rate (TSMAX to TP) Preheat: - Temperature min (TS min.) - Temperature max (TS max.) - Time (TS min. to TS max.
4 Module operation SPSGPE software architecture is based on SPSGPE.OS operating system and provides a set of precompiled firmware libraries to manage module operation. Two operational modes are supported: SPSGPE working as a “communication module”, using AT/HDLC commands; SPSGPE working as a “standalone module”, running embedded standalone application. When using SPSGPE as a communication module, the module acts as a wireless RF module. SPSGPE.
