This is one of our in-house projects—a wireless multimeter board based on ESP32, fully designed, developed, and produced by our engineering team.
We handled the entire process end to end:
-
✅ Circuit design: Our hardware engineers created the schematic with signal accuracy and safety in mind.
-
✅ PCB layout: We designed a compact, low-noise multi-layer board, ready for mass production.
-
✅ Firmware development: Our software team wrote the ESP32 firmware to support real-time data capture, wireless transmission via Wi-Fi/BLE, and communication with mobile apps or PC.
-
✅ Prototype testing: We built and tested full-function samples to verify measurement accuracy, stability, and wireless performance.
-
✅ Mass production: Once verified, we moved to small batch production with full quality control and documentation.
This board functions as a wireless multimeter, capable of measuring voltage, current, resistance, and temperature, with readings sent directly to a smartphone or cloud system.
Key Features:
-
ESP32 dual-core chip with Wi-Fi & BLE
-
Multi-channel signal acquisition (DC voltage, current, thermistor, etc.)
-
Rechargeable battery-powered with low-power mode
-
Mobile app connection for live data display
-
OTA firmware update support
Application Scenarios:
-
Smart electrician tools
-
Remote measurement in factories or labs
-
Portable diagnostic devices for field engineers
-
IoT monitoring where wired meters are not practical
This case proves our capability in custom hardware design, firmware development, and full-stack PCBA production. If you’re building smart measurement or sensor systems, we can help turn your idea into a working product—quickly and reliably.
