RAK2247 Pi HAT Datasheet

Overview

Description

RAK2247 Pi HAT is a converter board designed to allow the RAK2247 Concentrator module to interface with a Raspberry Pi SBC. It maps the 52-pin of mPCIe RAK2247 connector to the 40-pin Raspberry Pi header.

Moreover, there is a GPS on the HAT that enhances your RAK2247 with localization and timing data.

Features

  • Pi HAT form factor
  • mPCIe slot
  • GPS Module (MAX-7Q) module integrated into the HAT
