125kHz RFID board
125kHz RFID board

RFID is a type of communication in which information is transmitted wirelessly (Wikipedia article). Today, it is becoming increasingly popular and can be found in numerous and various cards: driving licenses, access control to buildings, public transportation, etc.

 

 

RFID readers come in many forms and variants. This reader, from our production, enables easy connection to a microcontroller, thereby opening up possibilities for developing various projects based on RFID technology. The breakout comes in two versions, and depending on the version, it is programmed and ready for communication via pins on the board. It has a switch for changing the data transfer speed (baud rate) as well as a connector for connecting the antenna that comes with the breakout.

GNSS GPS L86-M33 breakout with easyC
GNSS GPS L86-M33 breakout with easyC

Global Navigation Satellite Signal Systems (GNSS), or as we all like to call it “GPS”, enable precise location determination on Earth. Thanks to this module, you can use GNSS for your project and use the device for asset tracking or create a wearable device. The module is small, energy-efficient, high-performing, and easy to use thanks to the built-in antenna.

 

 

L86-M33 is a GNSS receiver, which means it can receive signals from GPS, GLONASS, and Galileo constellations. Equipped with EASY (Embedded Assist System for self-generated orbit prediction) and AlwaysLocate technologies, L86-M33 ensures fast and accurate positioning even in challenging environments. Its advanced internal logger LOCUS allows you to store your routes and location data.

 

 

Our breakout board, in addition to the previously mentioned L86-M33 module which has an integrated antenna, also has a connector for a CR1220 battery which is used as a backup for timekeeping and GPS data. The module can operate without the battery, but every time it will have to fetch data from satellites afresh (cold start). If the integrated antenna is insufficient, there is an IPX connector on the board for adding an external, stronger antenna. The antenna we suggest can be found here. To easily access the module pins, the pins are extended on the board for accessibility. There is also a switch on the board to change the I2C address.

USB-UART CH340 converter board
USB-UART CH340 converter board

This small USBUART adapter converts USB communication into UART (serial) communication, and everything you might need is already on this small board. In addition to the classic UART pins that are arranged in the standard layout: DTR, RXD, TXD, VCC, CTS, GND, other pins available of the CH340 chip are also available on header: RS232, RI, DCD, DSR, RST and CTS. Indication LEDs show activity on RXT and TXD lines, and a 500mA fuse protects this programmer, the USB port of the computer that is connected, and other devices connected to it from damage.

Additionally, there is a voltage regulator and a switch on the board, and it is possible to choose the output voltage of 3.3V or 5V, depending on the device you are using. The logic of the UART signal is always 3.3V, but don’t worry, 5V devices will work with 3V3 UART logic without any problems. Use a USB-C cable to connect.

Out of stock ESP8266 ESP-12 WiFi Module
ESP8266 ESP-12 WiFi Module

ESP8266 is an IC that delivers a true revolution in the world of makers, especially in the world of IoT (Internet of Things). This is a complete 32-bit SoC (System on Chip) with built-in flash memory, frame and EEPROM which can even be programmed directly from the Arduino interface, without the need for additional micro-controller. With all this, the most important point is that in itself has a built-in WiFi (AP, STA, AP + STA), all that for “little money”.

ESP8266 in this form (ESP-12) is suitable for direct soldering to a printed circuit board as an SMD component or directly solder the wires since the pin has its holes. It also comes with a PCB trace antenna.


 

Note: ESP8266 is an IC that works at 3.3V! Connecting directly to 5V, or track Arduino or Croduino plate will destroy it! Use logic level converter.

 

ESP32-WROOM-32D WiFi module
ESP32-WROOM-32D WiFi module

The ESP32 is a more advanced successor to the well-known ESP8266. It is a SoC (System on Chip) that can function as a standalone microcontroller and has everything you need on WiFi and Bluetooth 4.0 (BLE 4.0, low-energy) communication. With nearly 30 I / O pins and low power consumption, ESP32 will almost certainly be the leader in the Internet of Things for years to come.

The microcontroller itself works at a frequency of 160MHz (up to 240MHz), while the module has a built-in flash memory of 4MB. It has all the classic protocols like 4x SPI, 2x I2C, 4x UART, and there are many built-in peripherals like 18x 12-bit ADC, 2x 8-bit DAC, 10x capacitive touch GPIO, temperature sensor, SD card controller, Ethernet interface, PWM, etc. The list is really long. It should not be forgotten that this module has FCC certification and PCB trace antenna.
