Introduction

MDBT42T-AT and MDBT42T-PAT are Bluetooth 5.1 protocol stack modules designed based on the Nordic nRF52805 SoC solution, supporting Bluetooth Low Energy technology. The modules feature a compact form factor measuring 11.2 mm (L) × 7.2 mm (W) × 2.05 or 1.8 mm (H), and integrate a UART interface, functioning exclusively in peripheral/slave role for data bridging. Key advantages include: at 1 Mbps, the MDBT42T variant offers an open-space range exceeding 80 m, while the MDBT42T-P variant achieves up to 60 m; the Declaration ID covers all Nordic SoftDevices; and the modules have obtained certifications in major regions, including FCC (US), CE (EU), TELEC (Japan), SRRC (China), IC (Canada), NCC (Taiwan), and KC (Korea).
