Bluetooth modules

Bluetooth LE modules – a great comeback

Designers of radio modules and wireless communication protocols are well aware of the current trends in creating new mobile devices and electronics for everyday use. Their prototypes, and later mass-produced technologies, themselves contribute to the fact that we use these and not other solutions - all over the world. So, what to do, because the real popularity boom begins to affect Internet of Things projects? Modern programmable electronics and home automation systems, in a sense, force inventing new solutions. The overriding values ​​of the new technologies are the minimization of energy consumption, increasing the transmission range and increasing the level of data security.

All the above values ​​are represented by the latest Bluetooth - Bluetooth LE modules. Since the introduction of the official specification and the first modules implementing BLE 4.0 technology, we learn about the next version of Bluetooth almost every year. The new versions are much better in terms of link architecture and data security. All methods of Bluetooth communication are very low current today. Modern Bluetooth modules meet the requirements of even those users who have never liked this technology before!

Built-in Bluetooth modules

Today's Bluetooth modules come in many different versions. One of the most interesting forms that you will find in this Botland store category are built-in Bluetooth modules. These are special printed circuit boards with Bluetooth modules dedicated to be incorporated into a given structure. These are both components intended for soldering directly to the printed circuit board, as well as ready-made Bluetooth modules mounted on printed circuit boards. The Bluetooth kit for self-assembly and configuration includes all the necessary power circuits, digital connectors, antennas and even microcontrollers.

These types of devices can be installed both to a piece of furniture and to an existing device. Most often, however, we use such modules when prototyping new devices. If you are creating an IoT project or a walking robot that needs to communicate with other devices, a finished board with the latest Bluetooth version will be perfect!

In Botland, you can buy a variety of miniature modules that are easy to install in low-volume projects. Be sure to check out our miniature Bluetooth Low Energy (BLE 4.0) NRF51822 module. The module was embedded with soldering pads on a PCB with dimensions of 21x17mm. On the board you will also find some integrated microstrip antenna, so you won't have to worry about impedance and link performance issues.

Bluetooth modules with goldpin connectors

Among our modules you will also find practical devices equipped with goldpin connectors. A great example is the popular HC-05 v2 Bluetooth module, which has an angled goldpin strip. Thanks to this, you can quickly connect such a PCB to your programmable electronics. The connector is compatible with Arduino, Raspberry Pi or the board from the STM32 Discovery series. If you are looking for even simpler solutions, we recommend some Arduino base boards that are ready to run immediately after connecting the power supply. Some of these devices already have a built-in modern Bluetooth module in the BLE 4.0 version (similar to Wi-Fi). Another great example may be Bluno Mega 1280 BLE by DFRobot. In the other product categories of the Botland store you will find a lot of these types of PCBs. If you don't know what to choose, please feel free to contact us.
