MC-K45: SSC30KQ camera module with the 1/1.8 IMX347 sensor, now hard to find

Chip and memory
- SSC30KQ (I6E, 2xCA7) with 256MB DDR3 (https://t.me/c/1166652144/73003); a
  stock SSC30KQ firmware cmdline (board not named in the message) sets
  LX_MEM=0xffe0000 (https://t.me/c/1166652144/74585)
- "SSC30KQ max. 3K with 30 fps encoding" (https://t.me/c/1166652144/78910)

Sensor
- IMX347, 1/1.8 format, 2.9um pixel (https://t.me/c/1809358416/59868,
  https://t.me/c/1166652144/110555, https://t.me/c/1809358416/50389)
- "1/1.8 IMX347 can 4M@90fps (native) and 1080p@180 in window cropping
  mode"; Tino also gives SNR1 0.19 and 90fps all-pixel 10bit
  (https://t.me/c/1809358416/50389, https://t.me/c/1166652144/78910)
- It is not IMX415: Tino corrected a user who listed the K45 as SSC30KQ +
  IMX415 (https://t.me/c/1809358416/84692, https://t.me/c/1809358416/82262)
- Recommended for low light: "IMX347 Anjia MC-K45 (IMHO better)"

Interfaces and pinout
- On the stock firmware the drv_ms_cus_imx347_MIPI module reports
  i2c_slave_id 0, i.e. the sensor is on I2C bus 0 (measured)
  (https://t.me/c/1166652144/84224)
- MIPI CSI lanes: the stock driver parameter lane_num reads 2 (measured,
  2023-11), while the device tree has csi_sr0_lane_num = 4 (measured,
  2024-02); see Disagreements (https://t.me/c/1166652144/84244,
  https://t.me/c/1809358416/60946)
- "many Anjoy boards have +12V on board 4-pin USB instead of +5V or 3.3
  (e.g. K45)" (https://t.me/c/1809358416/113083)
- Lens mount: "22mm used with MC-K45", unlike the common 20 mm; "a rare
  thing: 22mm spacing + 1/1.8 sensor" (https://t.me/c/1809358416/51772,
  https://t.me/c/1809358416/73187, https://t.me/c/1809358416/26960)

Firmware support (OpenIPC / majestic / stock)
- The stock IPL_CUST can load U-Boot from the SD card (also eMMC), per
  strings in the stock IPL (measured) (https://t.me/c/1166652144/78074)
- OpenIPC (2023-10): "should be supported, but i'm not sure about high-fps
  sensor driver" (https://t.me/c/1809358416/29759)

Sourcing and price
- "K45 ~160RMB, MC800S ~150" in 2024-05; Tino recalled it earlier at ~205
  RMB (https://t.me/c/1809358416/81648, https://t.me/c/1809358416/81681)
- "MC-K45 with imx347 costs about the same as the MC800S" (2024-01)
  (https://t.me/c/1809358416/51762)
- Availability: "looks like EOL" in 2024-09; "almost impossible" to find in
  2024-10; "impossible to find it at the moment" in 2025-10

Disagreements
- MIPI lane count: Tino first wrote "looks like only 2l used on K45 while
  30KQ can 4" (2024-02-27), then after reading the device tree "looks like
  it could be 4" (2024-02-29); the stock driver parameter lane_num read 2 in
  2023-11 (https://t.me/c/1809358416/60246, https://t.me/c/1809358416/60946,
