+5-8 meter effective recognition distance with 100ms response time [citation:7]
+Complete RTOS SDK provided for quick custom command development [citation:9][citation:12]
+CH340C onboard serialto-USB for easy programming [citation:4][citation:9]
+Hardware noise reduction for reliable performance in noisy environments [citation:1][citation:6]
+Wake-up LED and status indicators for immediate feedback [citation:11]
√ Compatible with Arduino and other MCU development platforms [citation:4]
√ VC02 kit shares same base board as VC01 with compact module size [citation:8][citation:9]
√ Supports both English and Chinese language models [citation:9][citation:11]
The VC01 and VC02 kits use the same development board with different module footprints [citation:8]. For quick testing, the board comes preloaded with a demo firmware with "小安小安" wake word [citation:11]. Customize voice commands using the opensource SDK [citation:1][citation:2].
