Discuss customisation

Overview & features

A controller for addressable RGB LED strips built on the ESP32 family, with an audio front end modelled on Espressif's ESP-Korvo-1: an on-board microphone captured via ADC / I2S drives music-reactive effects, and reading the output current via ADC detects the number of LEDs. Supports RGBCW / RGBW / RGB wiring orders; buttons and an RF433 remote switch between 10 colour modes, 5 brightness levels, cycle intervals and static single colours. Wi-Fi / BLE are available in hardware for optional app control.

Key features

  • Microphone capture with audio analysis for music-reactive lighting
  • RF433 remote: mode ±, dim ±, on / off and pause, static single colours
  • Detects LED count via output-current ADC to suit different strip lengths
  • Switchable RGBCW / RGBW / RGB wiring orders; WW / CW mixing for warm and neutral white when channels are limited

FAQ

How soon will I hear back after submitting an inquiry?

Usually within 4 hours during working hours. For requests involving a custom solution, an engineer gets in touch within one working day to confirm the details.

Why doesn’t the site show prices?

Hardware and solution pricing depends on quantity, degree of customisation, certification and delivery requirements, so we issue a formal quote against each inquiry. Reference prices and MOQs for standard items are available when you inquire.

Is there a minimum order quantity?

Samples and small pilot runs are both available; the mass-production MOQ is stated in the quote and depends on the product and its materials.

Can you help with certification?

Yes. We arrange testing and certification for the target market — CCC, CE, FCC, SRRC, RoHS and others — with cost and lead time itemised in the quote.

Can the devices connect to our own cloud platform?

Yes. The firmware supports MQTT / HTTP integration with your own platform or a public cloud IoT platform; you can also use our cloud platform and mini-program monitoring service.

How do you handle after-sales support and firmware updates?

Mass-produced products come with OTA firmware updates and technical support; repairs and replacements are handled under the warranty period agreed in the contract.
