The products
Every product here opens to the industry behind it and the houses that own the design, in detail, with direct contacts.
The sensor behind the strap. ECG chest belts and optical armbands, ANT+ and BLE, a tight Bao'an sub-cluster in Shenzhen.
The chipset is the reference design. TWS, ANC and gaming headsets across the Shenzhen-Dongguan-Huizhou audio corridor.
A driver, an amp and a box around the same audio chipset. Outdoor boomboxes, party trolleys and pool floaters, the layer beneath JBL and Soundcore.
A capsule plus a chain to carry what it hears. USB studio mics, 2.4G wireless lavaliers and UHF stage systems, where Enping and Shenzhen design for everyone.
RTOS and Android, PPG and GPS and ECG. From kids GPS watches to medical-grade rings, the wearable layer beneath the brands.
The cell plus the power IC, and for GaN the power transistor. Tiny high-watt chargers and wireless banks, the layer beneath Anker and UGREEN.
Mechatronics plus credentials plus a cloud, on one door. Fingerprint, 3D face and RFID on Tuya or TTLock, the layer beneath Kaadas and Dessmann.
A camera, a radio and someone else’s cloud. The SoC-sensor-cloud stack beneath Ring and eufy, where GDPR is the real gate.
SmartPOS, PIN pads and EFT-POS. Home to two of the world's largest terminal makers, the moat is the certified secure platform, not the plastic.
Sonic and maglev drives, IPX7, induction charging. The manual brush belongs to Yangzhou, the electric one is designed in Shenzhen.
Four parts around the Cherry MX cross-stem, free since Cherry's patent lapsed. Linears, tactiles and magnetic rapid-trigger, the layer beneath Cherry and Keychron.
Switches dropped into a PCB, plate and case. Gasket customs, hot-swap gaming boards and magnetic rapid-trigger, from Akko and RK down to white-label OEMs.
Built around a PixArt sensor, raced on grams and hertz. 8K-polling ultralights and office combos, the layer beneath Logitech and Razer.
A Sony sensor and an ISP, in a waterproof shell. Budget GoPro alternatives and body cams, the layer beneath DJI, Insta360 and GoPro.
A flight stack, a gimbal and a radio link around one airframe. FPV, agriculture and survey, the niches DJI's shadow doesn't cover.
Forty joints, two computers and nothing to badge. The one product here with no reference design to buy, where the delta sells actuators and hands instead.
A mic, a speaker and somebody else's language model, wrapped in fur. Zhuhai silicon, Dongguan soft goods, and a child-safety gate that can switch your product off overnight.
Pendants and camera glasses that log a life for an agent to answer questions about. The platform is Qualcomm's and the brands are San Francisco's; the delta owns the optics and the build.
An IC costing cents, copper costing pennies and a certificate. The one product here with nothing to badge, which is exactly why it is the most substituted line on any BOM.
A watch with the screen deleted and the volume cut by ninety percent. The battery sets the design and Oura's patents set the market, as an ITC exclusion order proved.
The turnkey model in its purest surviving form, and the last computer you can still badge. Zhuhai silicon, Shenzhen glass, and Google's licence as the only real gate.
A motor, a cell and a moulding, sold by the tens of millions. The driver chip decides noise and runtime, and a 2027 EU rule ends the glued shell.
Ceramic atomisation, made in Bao'an for the world. The one category where the ODM outweighs its own customers, and where legislation decides everything.
The two-DIN DVD player became a cockpit platform. Two industries share this dashboard, the Huizhou tier ones and the Guangzhou aftermarket, and they barely touch.
Four Shenzhen houses hold over ninety percent of the world's entry-level machines. An open-source category, industrialised and then closed, now fought over in court.
Foreign silicon, Shenzhen everything else, and a vast carrier CPE trade behind the brands. In March 2026 the US barred foreign-produced routers on where they are designed.
The world's largest appliance base, concentrated in Shunde and Zhuhai. The compressor decides the product, and from 2027 the refrigerant forces it to be redesigned.
Portable boxes and wall batteries share a bill of materials and nothing else. The cell is a commodity, the hybrid inverter is the product, and every country's grid code is a separate door.
Nobody outside Shenzhen builds the emulation handheld as a product class. The hardware is legal, the library is the exposure, and a tariff line decides whether it ships.
A supercapacitor decides whether it survives a windscreen, and a far larger fleet telematics trade sits behind the retail camera. The one product whose legality changes at the border.
Guzhen in Zhongshan makes about half the world's lighting. The driver decides whether a lamp is any good, and EU flicker limits tightened in September 2024.
The one category where the platform is a quality system rather than a chipset, and the only one you cannot badge and ship. Mindray competes in the global top three.
A blade behind a foil or inside a rotary head, and thirty years of expired patents. The cluster is not in the delta; it is in Wenzhou and Ningbo, Zhejiang.
A spinning LiDAR, a brushless motor, a mop pad, and a dock that empties itself. The SLAM algorithm is the product, and Shenzhen-Dongguan owns the reference platforms behind the brands.
A light engine, a DMD chip or LCD panel, an LED or laser, in a box you can carry. TI DLP and LCD compete for the socket, with laser engines from Appotronics lighting the premium tier.
Three brushless motors, one IMU, and a control loop that holds the horizon. Camera, phone and action-cam stabilisers from a Shenzhen-Guilin axis that set the reference for the category.
A flash of light, a pulse of current, a wave of radio frequency, against the skin. IPL hair removal and LED therapy devices, the layer beneath the Japanese and Korean beauty brands.
A brushless motor, a percussion mechanism, and a stall force rated in pounds. The motor decides everything, and Shenzhen owns the fascia-gun reference design.
A feeder, a tracker, a camera, a litter box — connected. WiFi and BLE pet devices on Tuya, built across the Shenzhen-Dongguan corridor for every brand from Chewy down.
A sensor, a lens, an ISP, framed in USB-C. Sony IMX and OmniVision sensor modules, PTZ conference cameras and USB streaming cams, the layer beneath Logitech and Poly.
A fan, a HEPA filter, a carbon bed, and clean air. Shenzhen, Foshan and Guangzhou share the stack, with decades of OEM work for Philips, Honeywell and Haier.
Four load cells, an impedance circuit, and a Bluetooth radio. Zhongshan’s weighing heritage meets Shenzhen’s BIA electronics, the layer beneath Withings and Renpho.
A coin cell, a BLE radio, a speaker, and a network of billions. Apple Find My and Google Find My Device tags, MFi-licensed, UWB-ready, from Shenzhen’s BLE beacon cluster.
More products to follow. Each is added the same way: a specific product, the houses that own its design, verified, located and contactable.
