This document describes the features and characteristics of the EFM32-G8XX-STK Starter Kit, including advanced energy monitoring, on-board debugger, Energy Micro LCD, etc.
The EFM32‑G8XX‑STK starter kit provides a feature‑rich platform for evaluating and prototyping with Energy Micro's Gecko MCU family. It includes a 160‑segment LCD, touch slider, two user buttons, four LEDs, a 20‑pin expansion header, and on‑board USB debugging.
The manual covers power supply options (USB mini port or 20 mm coin cell), reset procedures, peripheral descriptions, and the Advanced Energy Monitor (AEM) that measures current consumption from 0.1 µA to 50 mA with high accuracy.
| USB power voltage | 3.15 V |
|---|---|
| Battery power voltage | ≈2.85 V (or lower) |
| Expansion header pins | 20 pins |
| User inputs | 2 buttons, 4 LEDs, touch slider |
| LCD type | 160‑segment Energy Micro LCD |
| Advanced Energy Monitor range | 0.1 µA to 50 mA |
| AEM accuracy above 200 µA | ±0.1 mA |
It can be powered via the USB mini port (3.15 V) or a 20 mm coin‑cell battery (≈2.85 V).
The AEM measures currents from 0.1 µA up to 50 mA.
The kit has four LEDs labeled LED0 to LED3.
The board controller resets only by pulling and reinserting the USB cable.
