Maxio: 1602 Full

If you are trying to run a "Full" test (testing the screen's maximum brightness):

The "Full" firmware shines under sustained loads. In consumer workloads (gaming, booting OS, launching browsers), the controller maintains sub-50ms latency. However, because it is DRAM-less, large file transfers (over 100GB) will eventually cause the SLC cache to fill, dropping write speeds to ~600–800 MB/s (direct-to-TLC write). The "Full" variant has a larger, more aggressive dynamic SLC cache compared to lite versions (often up to 1/3 of the total free space).

How does it stack up against the industry standard?

| Feature | Maxio 1602 Full | Silicon Motion SM2263XT | Realtek RTS5762 | Phison E13T | | :--- | :--- | :--- | :--- | :--- | | Architecture | 4-Ch, HMB | 4-Ch, HMB | 4-Ch, HMB | 4-Ch, HMB | | Sequential Read | 3,600 MB/s | 2,400 MB/s | 3,500 MB/s | 3,700 MB/s | | Max IOPS (Rand R/W) | 480k / 430k | 280k / 260k | 400k / 350k | 500k / 450k | | Power (Active) | ~3.8W | ~4.5W | ~4.8W | ~4.2W | | Encryption | TCG Opal 2.0 (Full) | AES 256 | AES 256 | TCG Opal (Limited) | | Price (Controller Level) | Low | Medium | Medium | High |

Analysis: The Maxio 1602 Full completely obliterates the older SM2263XT. It trades blows with the Phison E13T but offers better hardware encryption and lower power draw. For budget NVMe drives in 2024/2025, the Maxio 1602 is the gold standard.

The Maxio 1602 Full is famous for its close symbiotic relationship with YMTC (Yangtze Memory Technologies Co.) , China's leading NAND manufacturer.

Most "Maxio 1602" breakout boards have a similar layout. Check your specific board for labels, but here is the standard wiring:

Power:

Data Input (I2S):

Audio Output:

Gain/Mode Select (Optional): Some modules have a Gain pin. By connecting this to High or Low voltage, you can adjust the amplification volume (e.g., 6dB, 9dB, 12dB).
