Introduction

BT3L is a low-power embedded Bluetooth module. It primarily consists of a highly integrated Bluetooth chip TLSR8250F512ET32 and a minimal number of peripheral components, with a built-in Bluetooth network communication protocol stack and a rich set of library functions. BT3L also integrates a low-power 32-bit MCU, Bluetooth 5.0/2.4G Radio, 4Mbits flash, 48Kbyte SRAM, and 9 multiplexed I/O ports.
