The New WisBlock Modules Are Here! Let’s Click Code Connect Today!

We finally have the new WisBlock modules that will help you increase data security, and save your data locally on your device. We also created new sensors and a new type of touchscreen display.

At RAKwireless, we always try to make IoT easier for you and your projects, and we hope these five new modules will do that for you.

RAK14014 TFT Display

You might have seen this display from our RAK10701 Field Tester. The RAK14014 is a 240x320 pixel full-color TFT display with a touch screen and backlighting. Use it easily with its single-chip TFT-LCD controller FT6336 from Focal Tech which Arduino libraries support. Plus, the TFT display is mounted to a protective glass for our Unify enclosure.

The source code used in the example video is available on GitHub in the RAK4631-RAK14014-Demo repository.


  • 240x320 pixels touch screen display
  • Full view direction
  • Display Colors (Color Mode)
  • Full Color: 262K, RGB = (666) max., Idle Mode Off
  • Color Reduce: 8-color, RGB = (111), Idle Mode On
  • The backlight type is 4*LED (white)
  • Single-chip TFT-LCD Controller/Driver with On-chip Frame Memory (FM)
  • SPI interface
  • Display size 2.4 inch

RAK5814 Encryption Module

Using the Microchip ATECC608A, this module is the perfect companion if you need to secure your data before sending it over LoRa, WiFi, or BLE by decrypting them.

It integrates ECDH (Elliptic Curve Diffie Hellman) security protocol, an ultra-secure method to provide the agreement for encryption/decryption, and ECDSA (Elliptic Curve Digital Signature Algorithm) sign-verify authentication.


  • Cryptographic co-processor with secure hardware-based key storage
  • Protected storage for up to 16 Keys, certificates, or data
  • ECDH: FIPS SP800-56A Elliptic Curve Diffie-Hellman
  • NIST standard P256 elliptic curve support
  • SHA-256 & HMAC hash, including off-chip context, save/restore
  • AES-128: encrypt/decrypt, Galois field multiply for GCM
  • Turnkey PRF/HKDF calculation for TLS 1.2 & 1.3
  • Ephemeral key generation and key agreement in SRAM – Small message encryption with keys entirely protected
  • Full ECDSA code signature validation, optional stored digest/signature – optional communication key disablement before secure boot
  • Encryption/Authentication for messages to prevent onboard attacks
  • Internal high-quality FIPS 800-90 A/B/C Random Number Generator (RNG)

RAK13011 Magnetic Switch

This module is ideal for applications related to the opening and closing status of windows and doors, or even for the passage of objects in a production line. Using a simple Reed relay that reacts on the proximity of a magnet, it outputs a single signal that is high or low, depending on the status of the Reed relay. As an example, check out our Build a Door Open Counter and Alarm Sensor with WisBlock tutorial which includes a source code that you can immediately use and visualize the data with Datacake.


  • Standard Screw Fastening Reed Sensor with Cable Termination
  • Push-in termination of solid wires on the module, easy wire removal via the operating tool
  • Single GPIO Interface
  • 3.3V Power supply
  • Operating Temperature: -40° C ~ 85° C

RAK15004 FRAM Module

Introducing our Fujitsu MB85RC512T FRAM memory module as an alternative to our Flash, EEPROM, and SD card modules. Often, it is necessary to store data locally on a non-volatile memory on WisBlock. The FRAM technology offers advantages over Flash, EEPROM, and SD card modules with its low power, lifetime, and a superior number of write cycles.


  • I2C compatible digital interface
  • Operating power supply current 0.71 mA (Typ @3.4 MHz) 1.2 mA (Max @3.4 MHz)
  • Standby current 15 μA (Typ)
  • 64-kilo bytes / 512 kBit storage capacity
  • High Reliability:

o Read/ Write endurance. :1013 times/byte

o Data retention :10years(+85°C)

RAK12022 PT100 Temperature Sensor

Designed for rough environments, the PT100-type temperature sensors are perfect for industrial applications. This module has the MAX31965 resistance to digital converter. It is optimized for platinum resistance temperature detectors. The module supports 2-wire, 3-wire, and 4-wire PT100 sensors and has an SPI interface.

You can purchase the RAK12022 PT100 temperature sensor module combined with a PT100 sensor. You may also use your sensors, as an interface module only.


  • Based on MCP2518FD and ATA6563
  • Compatible with 2-, 3-, and 4-Wire Sensor Connections
  • SPI-Compatible Interface
  • 15-Bit ADC Resolution; Nominal Temperature Resolution 0.03125NC (Varies Due to RTDNonlinearity)
  • Total Accuracy Over All Operating Conditions: 0.5NC (0.05% of Full Scale) max
  • Fully Differential VREF Inputs
  • 21ms (max) Conversion Time

RAK12052 IR Array Sensor Module

RAK12052 is a 32x24 IR module based on MLX90640 from Melexis. The MLX90640 is a fully calibrated 32x24 pixels thermal IR array in an industry-standard 4-lead TO39 package with a digital interface. It's like those fancy thermal cameras, but compact and simple enough for easy integration, just in low resolution.


  • 32x24 resolution
  • Melexis MLX90640
  • Noise Equivalent Temperature Difference (NETD) 0.1K RMS @1Hz refresh rate
  • I2C compatible digital interface
  • FOV options – 55°x35°
