SparkFun Electronics ESP32 Thing Stackable Header Set 2x20 pin

Stackable Headers for ESP32 Thing

This set provides two 20-pin stackable headers designed specifically for the SparkFun ESP32 Thing. They enable a secure connection between the development board and compatible ESP32 Shield boards. Makers and engineers can quickly add power control, environmental or motion shields without soldering permanent joints. The headers keep the platform modular for iterative prototyping.

Build and Daily Handling

Each header uses a 1x20 pin layout with extended legs that accept another board on top. The 20 pins per strip match the ESP32 Thing edge footprint, so shields align without adapters. Gold-plated contacts resist oxidation during repeated mating cycles. The stackable height clears most through-hole components on the base board, keeping the assembly low-profile for bench use.

Thermals and Power in Use

The headers are passive copper alloy parts with no active cooling or semiconductor junctions. They add negligible series resistance to signal and power lines under normal shield currents. No fan, heatsink or external supply is required for the headers themselves. Temperature rise stays within the limits of the attached shields and the ESP32 Thing during typical development workloads.
