F1 Starter Kit
Introduction
The F1 Starter Kit is the evaluation board for the F1 Smart Module.
With Wi-Fi, BLE, LTE, and LoRa in one Arduino-compatible package, this development platform enables rapid prototyping and deployment of IoT applications requiring connectivity flexibility.
F1 Starter Kit
Varieties
Based on the cellular technologies and region, there are 4 varieties of F1 Starter Kit:
F1 Starter Kit NA, CAT-M1 (SGW3501-EVK-NA-CATM1-8130D)
F1 Starter Kit EU, CAT-M1 (SGW3501-EVK-NA-CATM1-8130D)
F1 Starter Kit Global, CAT-M1 (SGW3501-EVK-NA-CATM1-8130D)
F1 Starter Kit Global, NB-IoT (SGW3501-EVK-NA-CATM1-8130D)
Each Starter Kit comes with the following:
F1 EVK
CAP/T sensor
1-hour consultation
What Makes the F1 Starter Kit Unique
The F1 Starter Kit has four wireless protocols on a single board:
Wi-Fi for high-bandwidth local connectivity
BLE for low-power device interactions
LTE for reliable cellular communication
LoRa for long-range, low-power wide-area networking
Many connectivity decisions get made too early in development, locking you into assumptions without real-world data to back them up.
The multi-protocol approach with the F1 Starter Kit gives you the flexibility to choose the optimal connectivity solution for each specific use case, and test different protocols as your projects evolve. Need Wi-Fi for configuration but cellular for deployment? Both are right here. Want to add LoRa for remote sensors later? Already built in.
What to Expect in Development
Built with developer productivity in mind, look out for:
Arduino compatibility means your existing shields work without modifications. Same form factor, same pinout, same ecosystem you already know.
MicroPython support lets you prototype quickly without diving into Embedded C. Write readable code, iterate fast, and optimize later.
SG Ctrl Cloud Platform integration handles the device management, over-the-air updates, and data collection — everything to propel your prototype to production.

Pinout & Pin Definitions
All IO pins on the F1 Starter Kit can be MUXed to any digital function, while P19 and P20 are connected to the I2C lane of the on-board fuel gauge.
Analog and touch inputs should only be used on analog pins.
The mechanical arrangement of the pinout is compatible with standard Arduino UNO shields.
