1. Product Overview
WB3L is a low-power embedded Wi-Fi module that Tuya has developed. It consists of a
highly integrated RF chip (BK7231T) and several peripheral components, with an
embedded Wi-Fi network protocol stack and robust library functions. WB3L is embedded
with a low-power Arm Cortex-M4 microcontroller unit (MCU), 2 MB flash memory, 256 KB
static random-access memory (SRAM), and extensive peripherals.
WB3L is an RTOS platform that integrates all function libraries of the Wi-Fi MAC and
TCP/IP protocols. You can develop embedded Wi-Fi products as required.
