Sensor VCC → ESP32 power
Sensor GND → ESP32 GND
Sensor Signal → GPIO
using separate jumper wires every time, the expansion board provides grouped connections that make sensor installation faster and cleaner.
এতে multiple sensor বা servo connect করলে wiring অনেক সহজ হয় এবং project দেখতে organized থাকে।
Power Distribution / পাওয়ার কানেকশন
The board includes multiple power and ground distribution points, allowing several modules to share the same supply.
Typical connections may include:
• VCC – Power supply rail
• GND – Common ground
• B+ – Battery positive
• B− – Battery negative
• GPIO / Signal Pins – ESP32-C3 control signals
⚠️ Always check the printed PCB labels before connecting power.
Suitable for Servo & Sensor Projects
This expansion board is especially convenient for projects using multiple:
• Ultrasonic sensors
• IR sensors
• Servo motors
• Temperature sensors
• Light sensors
• Relay modules
• Joysticks
• Displays
• Other 3-pin modules
Because power, ground and signal connections are arranged together, wiring becomes easier than connecting everything directly to the microcontroller.
Why Use an ESP32-C3 Expansion Board?
ESP32-C3 boards are compact, which is excellent for small devices but can make wiring difficult when many sensors are connected.
The expansion board helps by:
✅ Increasing connection convenience
✅ Providing organized power rails
✅ Reducing loose jumper wiring
✅ Making debugging easier
✅ Improving project appearance
✅ Allowing easier module replacement
এই board ব্যবহার করলে ESP32-C3 project আরও neat, reliable এবং beginner-friendly হয়।
Important Compatibility Note
⚠️ ESP32-C3 development boards are available in different layouts and pin arrangements.
Before ordering, compare:
• Board size
• Header spacing
• GPIO arrangement
• USB connector position
• Pin labeling
with your ESP32-C3 board.
This expansion board should only be used when the physical pin layout and GPIO mapping match your development board.
Important Voltage Note
ESP32-C3 GPIO generally operates at 3.3V logic level.
⚠️ Do not apply 5V directly to ESP32-C3 GPIO pins.
⚠️ Some sensors may need level shifting when used at 5V.
⚠️ Servo motors or high-current modules may require a separate power supply.
⚠️ All connected circuits should share common GND where required.
Important Notes / গুরুত্বপূর্ণ নোট
⚠️ ESP32-C3 controller board is not included unless specifically mentioned.
⚠️ Check ESP32-C3 pin compatibility before installation.
⚠️ Confirm power polarity before connecting battery or external supply.
⚠️ Do not exceed the voltage/current rating of the connected ESP32-C3 board.
⚠️ High-current servo or motor loads should use a suitable external supply.
⚠️ PCB color, connector color and terminal layout may vary slightly depending on stock batch.
⚠️ Always follow PCB labels when wiring.
Frequently Asked Questions / FAQ
What is this board used for?
It is used to expand and organize GPIO, power and sensor connections for compatible ESP32-C3 development boards.
Does it include ESP32-C3 board?
No. This listing is for the expansion board only unless the ESP32-C3 controller is specifically mentioned.
Can I connect sensors directly?
Yes. The board provides convenient grouped GPIO, VCC and GND connections for compatible sensors.
Can I connect servo motors?
Yes, but use a proper external power source if the servo current is higher than the ESP32-C3 board can safely supply.
Does it have battery connection?
The board shown includes B+ and B− connection points for battery/external power connection.
Can I use it with every ESP32-C3 board?
Not necessarily. The physical pin layout and spacing must match your ESP32-C3 development board.
Does it support Arduino IDE projects?
Yes. The expansion board does not affect programming; the installed ESP32-C3 can still be programmed through Arduino IDE or ESP-IDF as usual.
