|Bluetooth Standard||DM 5.1|
The WG238 is a Bluetooth dual-mode 5.1 and Wi-Fi 802.11n module. The module integrates hardware and software resources needed to complete Wi-Fi and Bluetooth applications, supports AP and STA dual role connections, and supports both classic and low-power Bluetooth connections.
WG238 has a wealth of peripherals, such as PWM, I2C, UART, SPI, SDIO and IRDA. You can download and burn the program directly through UART. Up to six channels of 32-bit high-speed PWM output use the chip ideal for high quality LED control. Each 2 PWM can be configured for phase-controlled differential mode to support motor and lamp strip drives.
WG238 internally integrates priority-based Wi-Fi and Bluetooth coexisting control module to realize real-time priority and dispatch.WG238supports external PA and LNA extensions by providing an indication of the transceiver status of the current transceiver.
WG238 has built-in EFUSE and supports OTP reading and writing within Flash, which can be used to provide unique serial numbers, code encryption, and secure debugging interfaces. Internal integration of true random number generator and security module, ensure the security of communication and fast authentication and network connection.
The WG238 supports low-power sleep mode, and the MCU can enter the sleep state and reach the microamp level of sleep current. The WG238supports deep sleep mode, which can run 32 bit clock at several microampals of current and can be awakened by this clock or by any GPIO.
WG238is a compact WIFI module that supports 802.11b/g/n single-stream, low-power application processor. It is a low cost serial WIFI module that supports UART-WIFI-ethernet data transmission.
