概述

Description

BT840 commonly refers to a Bluetooth radio/module used in embedded/IoT projects. It’s a compact, low-power wireless transceiver that brings Bluetooth connectivity to a host MCU.
Key points:
- Wireless: operates in the 2.4 GHz band (BLE or dual-mode depending on variant).
- Interfaces: typically UART for data/control; some models offer SPI/I2C plus GPIOs.
- Power: low-voltage (often 1.8–3.6 V) with sleep/low-power modes.
- Configuration: firmware can be set via AT commands or an SDK; pairing and profiles (BLE GATT or Classic SPP) are supported per vendor.
- Applications: wireless sensors, beacons, wearables, remotes, and other IoT devices.
- Getting started: wire VCC/GND and TX/RX, set baud rate, load/configure firmware, and implement the desired Bluetooth services.
Note: exact specs (range, memory, supported profiles, and certification) vary by vendor—check the specific datasheet for your BT840 variant. If you share the manufacturer, I can tailor the brief precisely.

Package

There are multiple parts labeled "BT840." Please provide the manufacturer or full part number (or a datasheet link). With that I can tell the exact package type.

Pinout

BT840 pin count and functions depend on the exact device/package (there are multiple BT840 parts from different vendors). Please specify:
- Manufacturer and exact part number (or a datasheet link)
- Package type (e.g., QFN-XX, MSOP-XX, etc.)
With the datasheet, I can give the precise pin count and each pin’s function.
