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
Package Inclusion
- One (1) RAK2247 Pi HAT
