Ever wondered what hardware powers those compact ESP32 Smart Displays used in smartwatches, virtual knobs, touch dashboards, HMI interfaces, and IoT control panels?
In this ESP32-2424S012C Teardown, we completely disassemble and analyse the popular ESP32-2424S012C Smart Display Development Board. This board combines an ESP32-C3 microcontroller, a GC9A01 round IPS display driver, a CST816D capacitive touch controller, an IP5306 battery charger and boost converter, and a USB Type-C programming interface into a compact embedded system.
This is not a review.
This is a complete ESP32-2424S012C PCB Reverse Engineering and Circuit Analysis tutorial in which we identify major ICs, trace PCB connections, analyse the power architecture, and explain how the display, touch controller, charging circuit, and ESP32-C3 work together.
🛠 Teardown Highlights
✅ PCB top & bottom layer walkthrough
✅ GC9A01 display driver - COG (Chip-On-Glass) explained
✅ CST816D capacitive touch controller – COF (Chip-on-Flex)
✅ IP5306 battery charger + 5V boost converter circuit
✅ A6165P 3.3V LDO regulator
✅ ESP32-C3 pin mapping to display, touch, and UART
✅ Type-C USB programming circuit
