YiChip YC1155 Bluetooth 5.0 BR+EDR+BLE Dual-mode Module XY-MBZ55A1

XY-MBZ55A1 is a powerful, highly flexible, ultra low power Bluetooth 5.0 BR + EDR + BLE module based on YiChip YC1155 SoC solution.
Built-in 512KB Flash and 16KB+Data RAM, rich configurable peripheral interfaces, and RF transmit power adjustable from -20dBm to +9dBm, receiving sensitivity is -95dBm.
In addition, the module also integrates a high-precision crystal oscillator, an RF PCB printed antenna, industrial-grade design, RoHS process, half-hole pins for easy production processing.
XY-MBZ55A has rich interface resources, supporting UART, I²C, SPI, PWM, ADC, and other interfaces, which can be customized with customers’ individual needs and exclusive software; at the same time, the module has passed the system diversity compatibility test.

Key Features

Support OTA.

Support data transmission (GATT/GAP, custom UUID), BLE HID, etc.

Hardware interface: UART, multi-function GPIO, etc., and other rich interfaces.

Bluetooth RF performance is superior (transmit power up to 5dBm, receive sensitivity is -93dBm)

Good compatibility can be perfectly adapted to iOS/Android/Windows systems.

Compatible with 58A/87A modules package, you can directly replace the hardware if you want to achieve more complex Bluetooth
functions.

Typical applications: Bluetooth printer, 1 to 1 terminal connection printing, or high-speed Bluetooth upload terminal.
