Camera (OV2640 DVP 8-bit)
| Signal | GPIO |
|---|---|
| xclk | 15 |
| pclk | 13 |
| vsync | 6 |
| href | 7 |
| d2 | 11 |

| d7 | 18 |
| d8 | 17 |
| d9 | 16 |
| sda (SCCB) | 4 |
| scl (SCCB) | 5 |
pwdn and rstb are hardwired by R7/R8/R10, no GPIO needed. d0 and d1 are not connected (OV2640 outputs 8-bit only).
Shared SPI Bus (TFT + touch + SD)
| Signal | GPIO |
|---|---|
| sck | 39 |
| mosi | 40 |
| miso | 41 |
| lcdcs | 42 |

I2S Amp (MAX98357A)
| Signal | GPIO |
|---|---|
| din | 2 |
| bclk | 14 |
| lrclk | 48 |
sd_mode and gain are hardwired via R1, not software controlled.
Microphone (MAX4466)
| Signal | GPIO |
|---|---|
| mic | 1 |
Must be ADC1 (GPIO1-10) — ADC2 is unreliable with WiFi active.
LEDs (WS2812B)
| Signal | GPIO |
|---|---|
| led_data | 0 |
D5 → D6 → D7 daisy chained. One GPIO drives all three.
Pins Avoided and Why
| GPIO | Reason |
|---|---|
| 3, 45, 46 | Strapping pins |
| 19, 20 | Native USB D-/D+ |
| 35, 36, 37 | Internally wired to octal PSRAM on N16R8 |
Power
- Battery: 3.7V LiPo via JST PH 2.0mm (BT1)
- Charging: IP2312 module (U5) via USB-C
- 5V rail: MT3608 boost converter (U1) from battery
- 3.3V rail: onboard ESP32-S3 regulator
- 1.2V rail: NIC5365 LDO (U6) for camera
- 2.8V rail: MIC5504 LDO (U7) for camera
Flashing
Flash and monitor over the native USB port (GPIO19/20, labeled "USB" on the DevKitC-1). Do not use the UART port (labeled "UART") — GPIO43/44 are repurposed for SPI chip selects and that port will show garbage. Select USB CDC On Boot in your build config.

Questions
How big is the Digicamera PCB?
It measures 99 × 97 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Digicamera use?
90 parts, built around the MIC5365-1.2YC5-TR, MIC5504-2.8YM5-TR and WS2812B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Digicamera KiCad files?
From the vatsgoyal27/circuitbending_camera repository on GitHub, at the commit this page was made from: the board is digicamera/digicamera.kicad_pcb and its schematic digicamera/digicamera.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Digicamera design in my own project?
Its repository states no licence, so its author keeps all rights: ask vatsgoyal27 before reusing the design.
