Banana Pi M2 Magic development board was first unveiled in February of this year with an Allwinner R16 SoC, 512 MB RAM, and 8GB eMMC flash, and its main selling points were support for MIPI DSI LCD displays, CSI cameras, and 3.7V LiPo batteries. AFAIK SinoVoIP never sold that version of the board, at least on Aliexpress.
Possibly due to the intricacies of Allwinner business units, the company has now officially launched Banana Pi M2 Magic (aka BPI M2M), but replaced Allwinner R16 by the similar Allwinner A33 processor, and removed the 8GB eMMC flash to bring the price down to $23 plus shipping. The “old” Allwinner R16 based Banana Pi M2 Magic board will apparently be sold as M2 Magic Plus soon.
