AK-DS2480B-UART – 1-Wire to UART Converter€9.50
The AK-DS2480B-UART board converts the 1-Wire communication protocol into RS232/UART protocol and vice versa. It allows you to easily communicate with 1-Wire devices like temperature sensors and EEPROMs by using a serial port of your favorite microcontroller or with a PC/MAC/Raspberry Pi. If you already tried to implement the 1-Wire protocol by simply toggling a pin you probably realized that it requires a very strict timing, and basically when the 1-Wire communication is ongoing you had to prevent your program to do anything else but reading your 1-Wire device. Here the Artekit AK-DS2480B-UART comes to the rescue. It mounts the Maxim DS2480B chip, that uses a simple serial protocol and manages all the complicated timings. You will place the AK-DS2480B-UART board between a host (an Arduino UNO, for example) and the device (or devices) you want to talk to (for example a temperature sensor). The AK-DS2480B-UART board also provides the strong pull-up resistor needed to communicate with certain EEPROM and temperature sensors. We have prepared a practical guide with all the information and example code to get you started. The board breaks out the pins of the Maxim DS2480B chip into 0.1" (2.54mm) spaced pins. It comes fully assembled and tested. Note: if you are looking for a 1-Wire to I2C converter, we have that too! Please check out our Artekit AK-DS2482S-100 board.

AK-BTS716G – 4 Optically-Isolated Solid State Relays€24.90 – €28.40
The AK-BTS716G is a board with four optically-isolated solid state relays outputs. You can use it to power-up up to 4 devices that require 5.5V-40V DC, like DC motor, heaters, inductive and resistive loads in general. That is, you can connect an output of your Arduino or Raspberry Pi to this board and by toggling the output you can turn on and off a high power device. The board mounts an Infineon BTS716G high side power switch (the solid state relays) that provides 4 outputs with 5.5V-40V (maximum 1A) to your high-power devices. The BTS716G is optically-isolated from the rest of the circuit by a LTV-846S from LiteOn. This means that any noise produced by the high power device (especially when it's turned on and off) is completely isolated from your circuit, providing protection up to 5KV RMS. The usage is pretty simple: as you may know, an opto-isolator consists on an LED and a phototransistor. On the signal connector you can find the anodes and cathodes of the opto-isolator LEDs, and by turning these LEDs on and off, you enable or disable a high power output. A 330 Ohm for each of the 4 LEDs of the opto-isolator is already mounted on the board. You supply the voltage for the high power devices by using the connector on the side. There you will provide the 5.5V to 40V. The board comes with practical screw-terminal blocks already soldered in, for both power supply input and the outputs where you connect your high-power devices. For the input signals you can choose whether to include an industrial-grade Molex microfit connector (the black connector seen in the pictures, model 0436500800) you can assemble and solder. If you prefer to not use the connector, you can still use standard two-rows, right or straight angle header strips (1", 2.54mm pitch) for your connections. We have prepared a practical guide with all the information you need to get you started.

AK-MAX9814 – Microphone with High-Gain Amplifier and AGC€5.90
Even if it seems that this board is nothing more than a mic soldered into a PCB, there is more than meets the eye! The Artekit AK-MAX9814 is a board with an electret microphone coupled to a fully-featured high-gain amplifier: the Maxim MAX9814, capable of gaining 40dB, 50dB and 60dB and with Automatic Gain Control (AGC). Due to its high gain settings, this board is the perfect fit for ambient audio applications, but even if the board is placed close to the audio source, the AGC kicks in, avoiding saturation. The AK-MAX9814 is pretty simple to use. Just apply a power supply (2.7V to 5.5V typical) and select the gain with the GAIN pin: leave it open to set the gain to uncompressed 60dB gain, or connect it to GND to select 50dB gain or connect it to VCC to select 40dB gain. Additionally, the board has a A/R pin you can use to control the Attack-to-Release setting: leave it open to set A/R to 1:4000, or connect it to GND to set A/R to 1:500 or connect to VCC to set A/R to 1:2000. We have prepared a detailed user guide with all the information you need.

AK-3232L – TTL to RS232 Converter Breakout with LEDs€5.90
The AK-3232L is a TTL-to-RS232 converter board that converts UART TTL signals into RS232 standard communication signals. This allows you, for example, to connect a microcontroller UART to a RS232 port like the ones you can find in a PC. It is much like our AK-3232 board, but with the difference that this board has 4 LEDs to indicate the communication status. The LEDs will blink at every RX, TX, CTS and RTS signal positive transition (RS232). This board mounts an STmicroelectronics ST3232B, in charge of doing the 3V up to 5.5V into RS232 conversion. We also have TTL-to-RS232 converters but with a DB9 connector, with or without LEDs. The board has 0.1" (2.54mm) spaced pads, with two inputs and two outputs (so it can drive a full RS232, including CTS/RTS or DTR/DSR), and four mounting holes for easy mounting. We have a user guide that shows you how easy is to use this board.
