Description
The Nordic Semiconductor nRF52840 Mini is a breakout and development board for the nRF52840, a powerful combination of ARM Cortex-M4 CPU and 2.4GHz Bluetooth radio from SparkFun. With the nRF52840 at the heart of your project, you’ll have access to an almost limitless number of project possibilities in a surprisingly small package.
Most of the critical I/O pins, including GPIO and those required for power, are separated on our mini development board for the nRF52840, which has a footprint that is nearly identical to the Arduino Pro Mini (except those covered by the Qwiic Connector). It has a USB interface (which takes advantage of the nRF52840’s native USB support) that can be used to program, power, and communicate with the chip, allowing it to be used for any purpose (UART, I2C, SPI) that the Arduino Pro Mini can. A Raytac MDBT50Q-P1M module is included in the Pro nRF52840 Mini. This module connects the nRF52840 to a trace antenna, fits the IC into an FCC-approved footprint, and includes many of the decoupling and timing mechanisms that a bare nRF52840 design would require. A LiPo battery charger, a Qwiic connector, an on/off switch, a reset switch, and a user LED/button are also included onboard.
Applications:
- Smart home (such as door locks, lighting) sensors and controllers
- Industrial IoT sensors and controllers
- Health/fitness sensor and monitor device
- Wearables with wireless secure payment
Features:
- Low power requirements, ultra-low peak, average and idle mode power consumption.
- Be compatible with a large installed base of mobile phones, tablets, and computers.
- Fully coverage of BLE software stack.
- BLE & RF transmission switching helps products fit all operation systems and most hardware.

Features:
Package Includes:1 x SparkFun Pro nRF52840 Mini – Bluetooth Development Board | HC-02 Bluetooth serial communication module is based on the Bluetooth v2.0 Bluetooth protocol data transmission module, high stability, ultra-low power consumption, industrial-grade Bluetooth data transmission module. Users do not need to care about complex wireless communication configuration and transmission algorithms. They only need to connect to devices through the TTL serial port. Powered the HC-02 slave module, and can be connected to the mobile phone for data transmission. In addition, it can be used with HC-05 or HC-06 hosts (matching code, default is 1234) to connect, can replace a traditional serial line, save wiring work, use it’s very flexible. Pinout Diagram:How to Use the HC-02 Bluetooth module:The HC-02 has two operating modes, one is the Data mode in which it can send and receive data from other Bluetooth devices and the other is the AT Command mode where the default device settings can be changed. We can operate the device in either of these two modes by using the key pin as explained in the pin description. It is very easy to pair the HC-02 module with microcontrollers because it operates using the Serial Port Protocol (SPP). Simply power the module with +5V/+3.3V and connect the Rx pin of the module to the Tx of MCU and Tx pin of module to Rx of MCU as shown in the figure below During power up the key pin can be grounded to enter into Command mode, if left free it will by default enter into the data mode. As soon as the module is powered you should be able to discover the Bluetooth device as “HC-02” then connect with it using the default password 1234 and start communicating with it. Features

Package Includes:1 x HC-02 6pin Bluetooth Module Compatible with HC-05 / HC- 06 | HM-BT220X is a BLE data transmission module, based on a BLE 5.2 SoC chip (ARM Cortex-M33 32-bit processor, up to 76.8MHz working frequency), embedded with a 2.4GHz transceiver, equipped with an The Bluetooth technology manages the communication channel of the wireless part. The Bluetooth modules can transmit and receives the data wirelessly by using two devices. The Bluetooth module can receive and transmits the data from a host system with the help of the host controller interface (HCI). Features:

Packages Includes:1 x Bluetooth module HM-BT22014L. | The TTGO T-Beam offers 26-pin headers with GPIO, ADC, VP/VN, DAC, touch, SPI, I2C, UART, 2דLoRa” pin, and power signals (5V/3.3V/GND). There are also two buttons on the board—one is for power, but the second is connected to the GPIO39 pin of the ESP32. Pin Description:
The board is built around a dual-core ESP32 chip, with 4MB of SPI flash onboard, providing both Wi-Fi and Bluetooth LE via a “3D antenna” on the PCB. The board’s LoRa support comes in three different variants, operating at 433MHz, 868MHz, and 915MHz depending on region, with an included SMA antenna. While location tracking is provided by the onboard u-Blox NEO-6M GPS module with a ceramic antenna. The board can be programmed using the Arduino development environment, and the example code shows you how to both send and receive data via LoRa. Flipping the board over there is a battery holder for a 18650 Li-Ion cell, and while a 18650 sort of looks like a “standard” AA battery, it’s significantly different. So don’t make the mistake of substituting in the more common AA battery to try and power the board. They’re not quite the same size, but I’ve seen people attempt this substitution nonetheless.
