Dear John,

How are you! I hope you still remember me( Dennis ) from Tiny-Tech Embedded Inc.

We are pleased to inform you that we now have another EP9302 based SBC board named TB550. It's an enhanced version of the old TB550A SBC. From the attached document(TB550-HW-GUIDE.pdf), you could see the features about the board, and more information can be found from other attached documents.

We sincerely hope this SBC could become your choice for your applications.

We look forward to hearing from you soon.

Thanks and Best Regards,

Dennis Zhou
