Introduction
Planning a trip to China and looking to dive into hardware projects? Whether you’re experimenting with an ESP32 with TFT display or building a kiosk system for a project like display.regardingwork.com, China’s electronics markets are a goldmine. This guide covers costs, options, and tips for snagging the best deals on single-board computers (SBCs) and microcontrollers.
ESP32 with TFT Display: Costs in China
An ESP32 with an integrated TFT display (e.g., 2.8-inch or 3.5-inch, 240x320 or 480x320 resolution) is perfect for learning embedded software. In China, expect to pay:
- Online (Taobao, JD.com, AliExpress): 50-100 CNY ($7-14 USD) for basic models like ESP32-2432S028. Higher-end 5-inch capacitive touch models run 200-300 CNY ($28-42 USD).
- In-Person (Huaqiangbei, Shenzhen): Haggle for 30-70 CNY ($4-10 USD) in electronics markets like Shenzhen’s Huaqiangbei or Beijing’s Zhongguancun. Bulk deals often include extras like jumper wires.
Tip: Search “ESP32 TFT 显示屏” on Taobao for flash sales as low as 40 CNY. Local vendors in markets like Shanghai’s Pacific Digital Plaza can beat online prices by 20-30%.
Raspberry Pi for Remote Kiosk Displays
For a project like display.regardingwork.com, where you need to display numbers or data on old screens remotely, a Raspberry Pi is a solid choice. It’s ideal for a kiosk system—think digital signage pulling real-time data via a browser in fullscreen mode (e.g., Chromium with auto-refresh). The Pi’s HDMI output and Linux support make it perfect for old monitors, and it’s low-power with remote control options (SSH/VNC).
But is it the cheapest? Not always. Let’s compare low-cost devices for your kiosk setup:

Key Specs
Why Good for Kiosk
Price in China (CNY/USD)
Where to Buy
Raspberry Pi Zero 2 W
Quad-core ARM, 1GB RAM, WiFi, micro-HDMI
Ultra-cheap, low-power (5W), runs browser for data display. Limited for heavy graphics.
80-120 CNY ($11-17)
Taobao, Huaqiangbei, Xujiahui Computer City
Raspberry Pi 4 Model B (2GB)
Quad-core ARM, 2GB RAM, HDMI, WiFi/Ethernet
Best for smooth multi-screen setups; handles 1080p data feeds easily.
250-350 CNY ($35-49)
Taobao, official resellers; clones ~200 CNY
Orange Pi Zero 3
Quad-core Allwinner H618, 1-4GB RAM, HDMI
Cheaper Pi alternative; runs Armbian Linux for browser-based display.
99-150 CNY ($14-21)
Taobao (“香橙派 Zero3”), AliExpress, markets
Radxa X4
Intel N100 CPU, 8GB RAM, HDMI, WiFi
Outperforms Pi 5 for smoother rendering; x86 for advanced apps.
400-500 CNY ($56-70)
Taobao, Shenzhen suppliers
Android TV Stick/Box
Quad-core ARM, 2-4GB RAM, Android OS
Cheapest plug-and-play; sideload browser for web display.
50-150 CNY ($7-21)
Taobao, street markets, supermarkets
Recommendation
For budget-conscious projects, the Orange Pi Zero 3 (99-150 CNY) is ideal—half the price of a Pi 4 and capable of pulling data from your site via Python or a browser. Need more power? Go for the Raspberry Pi 4. For dirt-cheap, an Android TV stick works for simple web displays. Add a 5V USB adapter (10-20 CNY) and a case (20 CNY) to keep costs under 200 CNY ($28) per unit.
Cheaper No-Brand Alternatives in China
China’s markets are flooded with no-brand SBCs (e.g., Orange Pi, Banana Pi, NanoPi) that rival Raspberry Pi at 30-50% lower costs. In Shenzhen’s Huaqiangbei, grab an Orange Pi Zero for 50-80 CNY or a generic Rockchip board for 30-60 CNY. Online, Taobao offers Orange Pi 5 for 200-300 CNY or no-name RK3566 boards for ~100 CNY, running Android/Linux for signage. Avoid fakes under 20 CNY—they’re often underpowered.
Pro Tip: Mix and match—get an Orange Pi for your kiosk and ESP32s for software experiments. A bundle of 5-10 units can cost under 500 CNY ($70). Test compatibility with your project’s backend before scaling.
Conclusion
China is a hardware hacker’s paradise. From ESP32s at $4-10 to powerful SBCs under $70, you can build a robust kiosk system for display.regardingwork.com or learn embedded programming on a budget. Hit up Huaqiangbei or Taobao, and happy building!
