Ten small green circuit boards with pin headers and ESP32 chips

Vszerda

Vszerda D1 mini ESP32 ESP-32 WiFi+Bluetooth IoT development board 10PCS/LOT

SKU CH-SNFZ-CJCXD

Pack of ten ESP32 Wi-Fi and Bluetooth development boards for IoT projects

  • Ready-to-use 10-board lot accelerates IoT prototyping
  • ESP32 dual-core 32-bit processor handles Wi-Fi and Bluetooth tasks
  • ESP8266-compatible architecture simplifies existing code migration
  • Voltage regulator ensures stable operation for computer applications
  • Customised design fits specialised project requirements

10-piece ESP32 development board pack

This lot contains ten Vszerda D1 mini boards built around the ESP32 chip with integrated Wi-Fi and Bluetooth connectivity. Each unit is a fully functional IoT edge device aimed at makers, educators and prototype engineers who need multiple identical nodes for sensor networks, home-automation experiments or classroom projects. The boards arrive new and ready to program without additional components.

Upgrade from ESP8266-based modules

The design moves from the older ESP8266 architecture to the dual-core ESP32, adding Bluetooth support and more processing headroom for concurrent wireless tasks. The jump is worth it when a project requires both Wi-Fi and Bluetooth in the same sketch, or when the single-core ESP8266 struggles with TLS overhead and real-time sensor polling. Existing code written for the ESP8266 will need adaptation to the new SDK.

Ten boards give generous node headroom

Ten units in one lot cover a typical mesh deployment, a multi-room environmental monitor or a student lab bench with spares for damaged boards. Headroom runs out when a single application demands more than the available GPIO, flash storage or RAM on one board, or when the project scales beyond ten nodes and additional lots are required. No onboard battery management or high-current regulators are included.

Fragen zu diesem Artikel

What pin header spacing does the D1 mini ESP32 board use for shields or breadboards?

The board uses the standard D1 mini pinout so it fits existing shields and breadboards without adapters

How do I flash firmware onto the ESP32 module and what step often fails?

Connect the board via its micro-USB port, hold the BOOT button while pressing EN to enter download mode, then flash; forgetting to hold BOOT is the common mistake

Which on-board component will need replacement first in a long-running IoT deployment?

The flash memory on the ESP32 module wears out after many write cycles, so plan for board replacement if the application logs frequently
