Hangzhou Tuya Information Technology Co., Ltd. 1
V1.0.0
1 Product Overview
ZS2S is a low-power embedded Zigbee module that Tuya has developed. It consists of a
highly integrated Zigbee chip (EFR32MG21A020F768) and several peripheral circuits,
with an embedded Zigbee network protocol stack and robust library functions. ZS2S also
contains a 32-bit, 80 MHz, low-power Arm Cortex-M33 core, 768 KB flash memory, 64 KB
static random-access memory (SRAM), and extensive peripherals.
