Topwise A721

The "MID" formfactor was very popular in 2012. Therefor there are probably some variations with respect to the amount of NAND, camera and wifi modules.

There is some confusion, as to which device this is. The layout of the buttons and connectors seems to be compatible with the A710, but the board is crucially different.

In 2012, this board was also sold standalone, as the Gooseberry. The gooseberry forum now is abandoned and full of spam.

= Also known as =

There are probably tons of rebadgers, as this formfactor was very popular and got produced by several manufacturers.

Some possible suspects are:
 * Lyric F1 (LY-F1), which probably also shipped with an A710 board.
 * TomTop c1315
 * DVC z7


 * The bare board was also sold as the Gooseberry.
