CRG1 is a low-power embedded Wi-Fi + Bluetooth Voice module that T uya has de-
veloped. Embedded with the Wi-Fi network protocol stack and rich library functions,
it consists of a highly integrated RF chip (W701P-VA2-CG). With the maximum CPU
clock rate of 100 MHz, CRG1 also contains a low-power Real-M300 (KM4) microcon-
troller unit (MCU), a WLAN MAC, a 1T1R WLAN, a 8-MB pseudo-static random-access
memory (PSRAM), 4-MB flash memory, and rich extensive peripherals.
