ʻO ka Feasycom FSC-BT677D Silicon Labs EFR32BG21 BLE 5.2 & SIG Mesh & Multi-Connection Bluetooth Low Energy module me kahi microcontroller 32-bit 80 MHZ ARM Cortex-M33, hiki iā ia ke hāʻawi i ka mana kiʻekiʻe o 20 dBm. ʻO -97.5 (1 Mbit/s GFSK) dBm ka nui o ka loaʻa ʻana o ka chip, a kākoʻo ia i kahi aʻo DSP piha a me kahi ʻāpana lana no ka hoʻoponopono hōʻailona maikaʻi. Kākoʻo ka ʻenehana gecko haʻahaʻa i ka manawa ala ala wikiwiki a me ke ʻano hoʻōla ikehu. Kākoʻo ʻo FSC-BT677D lako polokalamu a me SDK iā Bluetooth Low Energy (LE), Bluetooth 5.2 a me Bluetooth mesh network. Kākoʻo pū ka module i ka hoʻomohala ʻana i nā protocol wireless proprietary. Hoʻohui pū ʻo FSC-BT677D i kahi MCU pili i ka ikehu me kahi transceiver radio i hoʻohui ʻia. Ua kūpono ka module no nā polokalamu ʻē aʻe i hoʻohana ʻia i ka pākaukau.
