Chapter 1 Feature
Lierda P-Series Low Power Consumption High performance Bluetooth transceiver Module
is designed based on TI CC2541 chip. The Module has ceramic integrate antenna, and
adopts SMT attachment interface. It has a complete open port which reduces hardware
design difficulties and also provide high structural and software flexibility for users. The
module has low power consumption, a compact size and have high resistance to disturbance.
Based on different kinds of application firmware, Product Model offered as sheet 1-1.
