Pin size and PCB drawing

PA control pin description
(1) The pins of PC2, PC3, PD2 are for PA use, they are not led to the module IO, do not use
(2) PD4 and PD5 are not led out.

Instructions for use
1) It is recommended to set the output power of CC2538 to + 3dBm, at this time the output power of the entire module reaches about + 20dBm.
2) The module can be pinned or soldered directly to the PCB of the product. If a PCB antenna is used, under the PCB antenna
There must not be any traces or copper clad. There should be no metal or magnet materials around the PCB antenna.
3) The standard SZ12 module comes with a PCB printed board antenna, including an IPX antenna base, and the default transmitting antenna is PCB
antenna. Users can choose IPEX-SMA double-headed feeder, external SMA antenna, this mode is suitable for
The module is installed in a strong shielding case, and the antenna is placed outside the case. When using this mode, it needs to be broken
Open the PCB antenna connection, and guide the RF signal to the IPEX seat.
The power supply voltage is + 3,3V, make sure the output current is> 175mA.

Minimum system circuit:

ESP32-WROVER-B is a universal Wi-Fi+BT+BLE MCU module. It uses a PCB onboard antenna and is equipped with 4 MB SPI flash and 3.3V, 64-Mbit SPI PSRAM. It is powerful and versatile. Used for low power sensor networks and extremely demanding tasks such as speech coding, audio streaming and MP3 decoding.

The chip used in the ESP32-WROVER-B is the ESP32-D0WD of the ESP32 series. The ESP32-D0WD chip is scalable and adaptive. Two CPU cores can be individually controlled. The CPU clock frequency can be adjusted from 80 MHz to 240 MHz. The user can turn off the power to the CPU and use the low-power coprocessor to monitor changes in the state of the peripheral or whether certain analogs exceed the threshold. The ESP32 also integrates a wide range of peripherals including capacitive touch sensors, Hall sensors, SD card interfaces, Ethernet interfaces, high speed SPI, UART, I2S and I2C.
