Why choose local ESP8266 and ESP32 stock
Get projects moving today - not next month. Our Samrand warehouse and branches carry a curated range of ESP8266 and ESP32 modules so you can prototype, teach or deploy without long import lead times. For students and makers, that means faster iteration and reliable VAT invoicing for tertiary purchases; for procurement teams it means easier quotes and bulk collection.
What we stock and who it's for
From compact ESP-01-style ESP8266 modules to dual-core ESP32-WROOM and low-power ESP32-C3 variants, we cover development boards, pre-flashed modules, breakout carriers, and recommended accessories such as USB-UART adapters, level shifters and antenna options. Browse the wider range of categories and filters at our Shop by Category to match parts to your use case.

Specification callouts you need to check first
Before ordering, compare key specs: core type, flash size, voltage domain, available GPIO, and antenna option. Below is a compact comparison table for quick reference.
| Module | Core | Typical Flash | Logic Voltage | Uses |
|---|---|---|---|---|
| ESP8266 (ESP-01) | Single-core 80/160 MHz | 1-4 MB | 3.3 V | Wi-Fi sensors, simple web clients |
| ESP32-WROOM | Dual-core Xtensa | 4-16 MB | 3.3 V | Real-time tasks, BLE + Wi-Fi |
| ESP32-C3 | RISC-V low-power | 4-8 MB | 3.3 V | Battery-powered IoT, secure apps |
If you need help selecting the right module for a class lab or a production pilot, compare specs side-by-side using our All Products index.
Accessory bundles and compatibility guidance
Common bundles that speed development: module + USB-UART adapter (FTDI/CH340), 3.3 V regulator breakout, and female header carrier. When pairing modules to shields or sensors, ensure logic-level alignment (3.3 V) and adequate current headroom - some cheap USB supplies struggle with Wi-Fi transmit peaks. For classroom sets, consider pre-flashed bootloaders and labelled breadboard kits to save setup time.
