MC-D40: Anjoy dual-sensor module on SSC30KQ with two GC2053 sensors on FFC
  camera modules

Chip and memory
- SoC is SSC30KQ (https://t.me/c/1809358416/291327,
  https://t.me/c/1809358416/72319, https://t.me/c/1166652144/74863)

Sensor
- Two GC2053 sensors on one SoC (https://t.me/c/1809358416/291327,
  https://t.me/c/1809358416/76993, https://t.me/c/1166652144/74863)
- Measured: stock firmware /opt/ch holds gc2053_MIPI.ko,
  gc2053_MIPI_master.ko and gc2053_MIPI_slaver.ko; replying to a remark that
  sensors should be synced in hardware, Tino said "because of this, the D40
  has two kinds of drivers" (https://t.me/c/1809358416/72319,
  https://t.me/c/1809358416/74000)
- Tino: "only 1080p and not sure about 90fpc"

Interfaces and pinout
- "the D40 / D80 have FFC (dual) camera modules"

Sourcing and price
- Taobao item 719006798593 (2024-02) (https://t.me/c/1809358416/60320)
- $25 on Taobao in 2026-06 for the bare module rather than a ready-made
  180-degree camera (https://t.me/c/1809358416/291327)
- ~$30 on Taobao without lens in 2026-10 (https://t.me/c/1809358416/299427)

Variants, aliases and products built on it
- Also sold as D40W (WiFi) and D40-4G (CN 4G)

Disagreements
- Sensor: the catalogue lists GC2063; Tino names GC2053 and the stock
  firmware ships gc2053_MIPI.ko (https://t.me/c/1809358416/72319,
  https://t.me/c/1809358416/76993)
- A 2026-10 message names the sensor less firmly ('2 x GC2039 or so') and
  the SoC as 'SSC30KD', against SSC30KQ and GC2053 elsewhere, including
  2026-06 (https://t.me/c/1809358416/299427,
  https://t.me/c/1809358416/291327)

Catalogue comparison
- The catalogue lists GC2063; Tino's evidence above gives GC2053
