+TP-Link Tapo C120
+---
+
+SoC SSC377, sensor SC430AI (4 MP), 16 MB NOR (XM25QH128C), Wi-Fi RTL8188FTV on USB.
+Firmware: the
+[`ssc377_lite_tp-link-tapo-c120`](https://github.com/OpenIPC/builder/tree/master/devices/ssc377_lite_tp-link-tapo-c120)
+device in OpenIPC/builder — 16 MB layout, `rtl8188fu` driver, WPA3-capable `wpa_supplicant`, the IQ file,
+and the IR-cut and LED pins. Take the image from the builder releases, or build it yourself with
+`./builder.sh ssc377_lite_tp-link-tapo-c120`. The SC430AI sensor driver lives in
+[OpenIPC/sensors](https://github.com/OpenIPC/sensors/tree/master/sigmastar/infinity6c). The generic
+`ssc377_lite` image is an 8 MB layout with no Wi-Fi driver and does not fit this camera.
+
+![Bottom side](../images/device-tapo-c120-bottom.jpg)
+
+### UART
+Five pads next to the flash chip on the top side: `VCC TP1 TP2 TP3 TP4`
+
+VCC | TP2 | TP3 | TP4
+-|-|-|-
+3.3V (do not feed) | TX | RX | GND
+
+115200 8N1. Connect RX (TP3) only after the camera is powered, otherwise it does not boot.
+
+Stock U-Boot stop string is `slp` (prompt `SigmaStar #`). It has `sf`, `md`, `mw`, `go` but no `mmc`/`fatload`.
+
+### Flash
+Dump the whole chip before writing anything. The OpenIPC bootloader image overwrites data the stock
+firmware needs to work, so only a complete backup lets you go back to Tapo.
+
+The builder image uses the standard OpenIPC 16 MB layout (`kernsize 0x300000`, `rootsize 0xa00000`):
+```
+mtdparts=NOR_FLASH:256k(boot),64k(env),3072k(kernel),10240k(rootfs),-(rootfs_data)
+```
+
+### Sensor
+Detection works by itself: `ipcinfo -s` prints `sc430ai`, and after start `logread | grep "Sensor index"`
+shows `2688x1520@30fps`. The builder device ships the IQ file as `/etc/sensors/sc430ai.bin`; on any
+other image take it out of your own stock firmware dump (`binwalk` finds the squashfs).
+
+### GPIO
+IRCut | IRLed | WhiteLed | RedLed | GreenLed | WiFi power
+-|-|-|-|-|-
+GPIO81 | GPIO12 GPIO13 | GPIO14 | GPIO10 | GPIO11 | GPIO42
+
+IR cut: high = day. LEDs: high = on. Speaker amplifier (GPIO48) is handled by the audio driver.
+
+```
+curl http://localhost/api/v1/config --data-binary @- <<'EOF'
+{
+  "nightMode": {
+    "irCutPin1": 81,
+    "irCutSingleInvert": true,
+    "backlightPin": 14
+  }
+}
+EOF
+```
+
+---
+
+### Wireless
+The RTL8188FTV is powered through GPIO42; the builder device's `/etc/wireless/usb` has the entry:
+```
+if [ "$1" = "rtl8188fu-tapo-c120" ]; then
+	set_gpio 42 1
+	sleep 2
+	modprobe 8188fu
+	exit 0
+fi
+```
+
+```
+fw_setenv wlandev rtl8188fu-tapo-c120
+fw_setenv wlanssid Router
+fw_setenv wlanpass 12345678
+```
+
+Driver: `BR2_PACKAGE_RTL8188FU_OPENIPC=y` (`8188fu` from openipc/realtek-wlan, branch `rtl8188fu`).
+The device selects `BR2_PACKAGE_WPA_SUPPLICANT_OPENIPC=y`, a wpa_supplicant with SAE, but the stock
+`wlan0` script still writes a WPA2-PSK config: a WPA3-only network needs `key_mgmt=SAE` in
+`/tmp/wpa_supplicant.conf` until that script learns it.
+
+### Ethernet
+`J2` (marked ETH) on the bottom side has TX/RX from the internal PHY, no connector fitted.
