1 Device Overview
1.1 Description
XY-MBA32A is a powerful, highly flexible, ultra-low power Bluetooth® 5.1 module based on ASR
Technology ASR5601C, which has an Arm® Cortex™-M0+ CPU with the floating-point unit running at 64MHz.
Built-in 512KB Flash, 96KB SRAM, rich configurable peripheral interfaces, and high-performance low-
power Bluetooth RF, transmit power adjustable from -30dBm to +10dBm, receive sensitivity of -98dBm. In
addition, the module also integrates a 16MHz crystal oscillator and IPEX port(RF PCB printed antenna),
industrial-grade design, a RoHS process, and half-hole pins for easy production processing.
