AT-09 BLE Bluetooth 4.0 Module TI CC2541
The AT-09 is a module that contains a BLE chip (a CC2540/CC2541). This module allows to perform serial communication with the BLE chip thanks to an Rx and a Tx pin. This module is also very similar to the HM-10 module and is also compatible with it. So if you have some experience with the latter, you will get started quickly with the AT-09.
Features: This small size Bluetooth 4.0 transceiver module allows your device communicate with IOS Android, Arudino and others This module uses the JDY-09 Breakout It is easy to use and completely encapsulated. You can set it as slave or master. You can use AT command set the baud rate. Ultra-low standby power consumption 90uA-400uA, built in PCB antenna, has a built-In Level Switch Function
- Input Voltage: DC 3.3V/5V
- Uses CC2541
A little about the CC2541:
The CC2541 is a power-optimized true system-on-chip (SoC) solution for both Bluetooth low energy and proprietary 2.4-GHz applications. It enables robust network nodes to be built with low total bill-of-material costs. The CC2541 combines the excellent performance of a leading RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8-KB RAM, and many other powerful supporting features and peripherals. The CC2541 is highly suited for systems where ultralow power consumption is required. This is specified by various operating modes. Short transition times between operating modes further enable low power consumption.
