Buy IoT Boards, ESP32 & Wireless Modules in Ghana
The future is connected. At DIYGH, we provide the essential communication modules for engineering students and developers in Kumasi and across Ghana. Whether you are building a smart home system or an agricultural monitoring device, we have the connectivity you need.
Which Wireless Module is Right for You?
1. Wi-Fi Boards (The IoT Standard)
- ESP8266 & NodeMCU: The most affordable way to get your project on the internet. Perfect for beginners building basic web servers or Wi-Fi controlled lights.
- ESP32 Development Boards: The dual-core powerhouse. It has built-in Wi-Fi and Bluetooth. Ideal for cameras (ESP32-CAM), complex web dashboards, and heavy processing tasks.
2. GSM & Cellular (For Remote Areas)
- SIM800L & SIM900: Essential for projects that need to work where there is no Wi-Fi. These modules allow your Arduino to send and receive SMS text messages or use mobile data—very popular for smart agriculture projects and fire alerts in Ghana.
3. Radio Frequency (RF) & Bluetooth
- NRF24L01 Transceivers: The best choice for communication between two Arduinos (like a remote control car) without using the internet.
- HC-05 & HC-06 Bluetooth: Add phone control to your robot. These modules let you control your project using a smartphone app.
Why Buy IoT Parts from DIYGH?
Wireless modules can be tricky to set up. We stock boards that are tested to work with the Arduino IDE and MicroPython, ensuring you don't struggle with driver issues or bad chips.
