Ko te Feasycom FSC-BT677C Silicon Labs EFR32BG21 BLE 5.2 & SIG Mesh & Multi-Connection Bluetooth Low Energy kōwae kei roto i te 32-bit 80 MHZ ARM Cortex-M33 microcontroller, ka taea te whakarato i te putanga mana teitei o te 10 dBm. He -97.5 (1 Mbit/s GFSK) dBm te morahi o te maramara, me te tautoko i te ako DSP oti me te waeine-iti mo te tukatuka tohu pai. Ka tautokohia e te hangarau mokoko hiko iti te wa oho me te aratau whakaora hiko. Ko te rorohiko FSC-BT677C me te SDK e tautoko ana i te Bluetooth Low Energy (LE), Bluetooth 5.2 me te whatunga mata Nihokikorangi. Ka tautoko hoki te kōwae i te whanaketanga o nga kawa ahokore rangatira. Ko te FSC-BT677C te whakakotahi i te MCU pai-kaha me te whakawhiti irirangi tino whakakotahi. He pai te kōwae mo tetahi tono e whakahaere ana i te pākahiko i etahi atu punaha e hiahia ana kia kaha te mahi me te iti o te whakapau kaha.
