It also includes an optional serial Flash (1MB or 2MB), an on-board chip antenna and a u.FL connector for optional external antenna. Voltage Input RZ707 Module supports a flexible power supply. VBATT_WLAN, required for the Wi-Fi device, can be in the range of 2.7V to 4.8V. VBATT_MICRO can be in the range of 1.65V to 3.6V. Vdd, used by the microcontroller and the optional flash, can be in the range of 1.8V to 3.6V. I/O Interface STM32F205RE/RG offers a host of interfaces enabling a rich and flexible hardware design. These include not only the standard interfaces such as UARTs, SPIs, I2C, I2S, GPIOs, ADCs, DACs, and Timers but also USB for easy connectivity for data and provisioning.
ReZolt RZ707 Em-Fi Module User Manual 7 RZ707MS-UM-081312 Radio Frequency BCM43362 Wi-Fi device supports 802.11bgn with the latest Wi-Fi functionality including security and provisioning and enabling a broad range of embedded Wi-Fi products. This module operates within the frequency range between 2412 and 2464 Mhz, which correspond to the central frequency of channel 1 and channel 11 for IEEE 802.11 b/g/n standard. Chip Antenna The chip antenna included on the module (which is also used for FCC test) is manufactured by Johanson, with part number 2450AT42B100E. The datasheet of the antenna is attached to this document. Crystals There are three crystals used on the module. Two crystals connected to STM32F205RG work at 16 Mhz and 32 Khz, respectively. The single crystal connected to BM43362 works at 26 Mhz. STM32F205RG has an internal PLL circuitry, which works at 96 Mhz when it is turned on. Radio Power A piece of software runs on STM32F205RG to control the radio operation. By default, the software always transmits at full power (which is used during test for FCC certificate). ReZolt provides software API to customers in order to lower down the transmission power from the default state, but never beyond the default state. Specifically, following function is provided to customers in order to lower the radio transmission power from the default number: Status wdd_adjust_tx_power(uint8_t pwr), where parameter pwr is in unit of dBm and always capped by the default power number when the software processes this function call.

ReZolt RZ707 Em-Fi Module User Manual 11 RZ707MS-UM-081312 5 Installation Guidelines 5.1 Layout Guidelines The module footprint is shown in the above figure. There are two ways of using/connecting antennas
ReZolt RZ707 Em-Fi Module User Manual 12 RZ707MS-UM-081312  To use the on-module chip antenna. In this case, the Antenna Area labeled above needs to be kept clear of copper to ensure good RF performance.  To use external antenna, via the u.FL coax connector. In this case, it is OK to overlap the Antenna Area with copper. However, to ensure the external antenna meets the requirements of MIC/TELEC, the user needs to contact ReZolt Corporation with detailed specification of the antenna. In addition to the above guidelines, note the following suggestions:  Place external bypass capacitors as close as possible to the module pins.  To achieve better communication quality, keep metallic objects away from the antenna (either the on-module chip antenna or external antennas) as far as possible. 5.2 Surface Mount Assembly Table below lists recommended reflow parameters.
