Find the right ESP8266 and ESP32 modules locally
Get immediate access to the WiFi and Bluetooth SoMs and development boards you need - stocked in South Africa for same-week collection or national delivery. Communica specialises in sourcing a broad range of ESP8266 and ESP32 modules, breakout boards and companion parts so your prototype, classroom lab or production build keeps moving. Benefit from local availability, VAT invoices for procurement, and branch collection from Samrand, Pretoria CBD or Cape Town.
Why choose local stock for ESP modules?
Sourcing locally reduces lead times, simplifies returns and gives you access to hands-on advice when you need it. Whether you are a tertiary lab ordering multiple units or a maker buying a single NodeMCU board, local supply means predictable delivery and easier bundling of power, sensors and antennas.
Common module types and quick spec callouts
Below are practical, side-by-side characteristics to guide selection. All modules are widely compatible with Arduino, MicroPython and ESP-IDF workflows, but pinout and power requirements differ.
| Module | Core | Wireless | Voltage | Use cases |
|---|---|---|---|---|
| ESP8266 (ESP-12E/F) | 80/160 MHz | 802.11 b/g/n | 3.3 V | Simple WiFi sensors, web dashboards |
| ESP32-WROOM | Dual-core 240 MHz | WiFi + Bluetooth Classic/LE | 3.3 V | Audio, BLE beacons, advanced IoT |
| ESP32-S3 | AI-accelerated cores | WiFi + BLE 5 | 3.3 V | ML inferencing, cameras |
Selection criteria - what to check before you buy
- Interfaces: UART, SPI, I2C and ADC availability vary by module package.
- Power budget: check peak WiFi transmit current (up to ~500 mA) and size power supplies accordingly.
- Antenna type: PCB vs u.FL vs external - choose for range or compactness.
- Flash size and PSRAM: critical for camera or OTA update use.
- Regulatory and deployment: plan enclosures and external antennas for range-critical installs.
If you need a quick parts bundle for development, we stock compatible USB-to-UART adapters, 3.3 V regulators and prototyping headers so you can plug a module straight into a breadboard or carrier board.
