The WisBlock RAK11200 Wi-Fi & BLE Core Module provides a flexible platform for custom sensors, connected displays and control devices using Wi-Fi or Bluetooth.

Built around the Espressif ESP32-WROVER, it combines a dual-core processor running at up to 240MHz, 4MB Flash, 520KB RAM and 8MB PSRAM for sensor processing, wireless communication and custom application functions.

Use 2.4GHz Wi-Fi to connect your device to a suitable network, or Bluetooth Classic and BLE to communicate with nearby compatible devices. Its built-in PCB antenna means no separate Wi-Fi/Bluetooth antenna is needed.

Develop your application using Arduino IDE or PlatformIO. A compatible WisBlock Base Board provides power, programming access and expansion for sensors, interfaces and displays.

End of Life – Remaining UK Stock

RAK announced the RAK11200’s end of life in October 2025, naming the RAK3312 as its successor. Our remaining stock is available for existing projects, replacements and compatible builds. Need larger quantities? Please contact us. We can help source additional units while RAKwireless stocks last, subject to availability. For new designs, see the WisBlock RAK3312 ESP32-S3 LoRaWAN Module.

Start with a Base Board – Required

RAK19007 WisBlock Base Board – 2nd Generation – versatile starting point with sensor and IO expansion

RAK19003 WisBlock Mini Base Board – compact builds with fewer modules

RAK19001 WisBlock Dual IO Base Board – larger builds needing two IO slots

View all WisBlock Base Boards →

Check access to the base board’s BOOT0 and GND connections for firmware uploads.

Add Sensing & Location

RAK1901 Temperature & Humidity Sensor – indoor climate monitoring

RAK1906 Environmental Sensor – temperature, humidity, pressure and gas sensing

RAK1904 3-Axis Acceleration Sensor – movement, tilt and vibration

RAK13003 WisBlock IO Expansion Module – additional digital inputs and outputs

RAK1921 WisBlock OLED Display – local readings and device status

RAK18001 WisBlock Buzzer Module – audible indications

Check base-board slots, ESP32 pin assignments and firmware examples when combining modules.

Add LoRa Connectivity

The RAK13300 WisBlock LoRaWAN Module adds an SX1262 LoRa radio to a compatible RAK11200 build.

Use a base board with a suitable IO slot, such as the RAK19007, together with compatible firmware and the correct antenna. For UK LoRaWAN projects, select an EU868 configuration.

Power Your Build

Battery Connector Cable – Pack of 5

5V Solar Panel – 80 × 45mm

Choose a compatible battery and charging arrangement for your base board. Allow for Wi-Fi transmission current when sizing the supply.

📍Check battery connector polarity before connecting.

House Your Device

Browse Enclosures →

Check mounting provision and space for your assembly, battery and cables. Keep the PCB antenna clear of metalwork and other obstructions.

Which Core Should You Choose?

Choose this RAK11200 for an existing ESP32-WROVER project, a replacement Core or a compatible Wi-Fi/Bluetooth build.

Choose the WisBlock RAK3312 for a new ESP32-S3 project combining onboard LoRa, Wi-Fi and BLE, with more Flash memory.

Choose the WisBlock RAK4631 Arduino EU868 for low-power remote sensors using onboard LoRa and BLE.

The RAK3312 is RAK’s named successor, but is not a direct firmware replacement. Check libraries, pin assignments and application requirements before changing Cores.

End of Life – Remaining UK Stock

The RAK11200 has reached end of life following Espressif’s discontinuation of its ESP32-WROVER module. Existing users remain supported through RAK’s documentation and resources.

Our remaining UK stock is available for existing projects and replacements. For new designs, consider its successor, the WisBlock RAK3312. Check firmware, libraries and pin assignments before changing Cores.

A compatible WisBlock Base Board is required and is sold separately.

This is the standard RAK11200, SKU 110023. It does not include the Cyberon voice-processing licence supplied with the separate voice-processing version.

Manual download mode is required for wired firmware uploads. Follow RAK’s guide to connect BOOT0 to GND and press reset before uploading. The included headers and jumpers can help provide access; fitting headers may require soldering.

The Wi-Fi/Bluetooth antenna is built in. No separate antenna or MHF cable is required for the supplied PCB antenna.

Wi-Fi operates at 2.4GHz. Your network must support a compatible 2.4GHz connection.

There is no onboard LoRa radio. LoRa or LoRaWAN operation requires additional compatible radio hardware and firmware.

Battery life depends on wireless activity, reporting intervals, connected modules and sleep configuration. The published ESP32 deep-sleep figure is not the consumption of a complete WisBlock assembly.
