  • The motherboard is secured under a nice metal shield, likely for heat dissipation and probably structural support.

  • De-shielded we see the mighty fields of... wait these look like chips we've seen before.

  • Allwinner R16 quad core ARM Cortex A7 processor with a Mali-400MP2 GPU core

  • 512 MB of Macronix MX30LF4G18AC 4 Gb NAND Flash memory (as opposed to the Spansion branded memory found in the SNES)

  • 256 MB of SK hynix 2 Gb DDR3 SDRAM (H5TQ2G63GFR-RDC)

  • X-Powers AXP223 Power Management IC

  • Richtek RT7295A 3.5 A synchronous step-down converter

基板は美しいメタルシールドの下に搭載されています。これは構造上のサポートだけでなく、放熱の役割があるようです。

シールドを取ると前に見たことがあるチップのフィールドが待っています。
