Why choose ESP8266 and ESP32 modules from a local supplier
Get your Wi-Fi and Bluetooth IoT hardware today without long import delays. South African makers, students and engineering teams need reliable local stock, VAT-ready invoices and branch collection options - not vague ETA estimates. We stock a broad selection of ESP8266 and ESP32 variants suitable for classroom prototyping, proof-of-concept builds and small-batch production. For an overview of our company and history in local distribution, see our About Us.
Immediate benefits
- Local stock reduces lead times for semester projects and client deliveries.
- Branch pickup from Samrand, Pretoria CBD or Cape Town avoids courier delays (see branch hours).
- Component breadth: modules, dev-boards, headers, enclosures and power accessories in one place.
Common module types and where to use them
Choose by radio, GPIO count and package. Typical options we supply include flash-memory variants of ESP8266 (low-cost Wi-Fi for sensors and simple web UIs) and multiple ESP32 flavours (dual-core, BLE, more ADCs and peripherals). For shopping and to compare categories, visit Collections and the Shop by Brand page to see supported manufacturers and maker favourites.
Specification callouts to check before you buy
| Characteristic | Why it matters |
|---|---|
| Flash size (e.g., 4MB) | Determines OTA space and ability to run larger frameworks like MicroPython or full Arduino builds. |
| Number of GPIOs / ADC | Affects sensor count and analog inputs for battery sensors and analog circuits. |
| Wireless features (Wi-Fi 2.4GHz, BLE) | Choose BLE for proximity beacons or dual-mode for mobile + cloud integration. |
| Power input (VBAT, 5V USB) | Impacts power supply selection, battery options and regulator heat dissipation. |
Wiring example - connect a basic sensor to an ESP32 dev board
ESP32 VIN (5V) ---- USB 5V supplyESP32 GND --------- Sensor GNDESP32 3V3 --------- Sensor VCC (if 3.3V)ESP32 GPIO34 ------ Sensor Analog out
Most modules are 3.3V logic - use level shifters for 5V sensors. For parts and accessories to assemble your kit, browse our All Products list.
