11 / 27 page DocID026906 Rev 4 11/27 SP1ML Hardware design 27 2.2 Typical application circuit In a typical application the SP1ML module is connected to a host MCU using a standard UART, with transmit and receive signals. This is illustrated in Figure 3. Figure 3. Typical application circuit Optional functionality 1. When the TXRX_LED (S24) configuration register (see Table 10) is set to 1, the TXRXLED signal is an active-low open drain output that can be used to drive an external LED for status indication when data is sent or received. 2. The MODE0 signal provides a hardware method for switching between command and operating modes. The SHDN signal allows the module to be placed into a low power shutdown mode and woken up again. 3. The BOOTMODE AND RESET signals should be connected if module firmware will need to be updated over the UART interface. 4. To support custom module firmware, the serial wire debug signals need to be accessible for programming and debugging. 2.3 Layout guidelines The application PCB requires a flooded ground plane. Care must be taken to ensure there are no traces or ground planes under the area surrounding the antenna, with the exception SP1ML MODULE HOST MCU TXD TXD RXD RXD RTS CTS GPIO GPIO BOOTMODE RESET GPIO GPIO MODE0 SHDN TXRXLED 1 2 3 VDD RESET SWCLK SWDIO 4 SWD HEADER VDD VDD VDD GND 10uF |
