Note: For best performance, we now ship Explorer Hat with the perfect antenna for your operating frequency. Be sure to select the right one! Select 868MHz for 868-869MHz, and 915MHz for 902-928MHz!

Introducing the 900MHz Explorer Hat! Now you can use buttons and a screen to explore the 900MHz radio band with your Raspberry Pi Zero W or Raspberry Pi 3.

We are currently accepting preorders with availability in April. Get first in line by pre-ordering now! Make sure you select the proper frequency for your region!

Please note: due to restrictions on Raspberry Pi Zero W distribution, we are unable to bundle this with the Raspberry Pi Zero W. This is for the 900MHz Explorer Hat only. For a soldering-free experience, we suggest purchasing the new Raspberry Pi Zero WH (with headers soldered on!). You can find Raspberry Pi Zero WH at many great retailers, such as Adafruit¹ -- or other distributors throughout the world
