To ensure the board fits properly, I need to verify if the mounting holes on the EVM will align with the standoffs in my enclosure. Could you please provide the following mechanical specifications for the DRV8803EVM? Hole-to-hole dimensions: The distance between the mounting holes. Hole specifications: The diameter of the mounting holes (and whether they are plated through-holes or threaded). If a mechanical drawing (such as a PDF or DXF file) containing these dimensions is available, it would be extremely helpful. Thank you for your assistance. I look forward to your reply.

I am currently designing an enclosure to house the DRV8803EVM for a project. To ensure a proper fit, I need to secure the board using the mounting holes. However, I have been unable to find the specific dimensions and specifications for these holes in the publicly available documentation. Could you please provide the following details: The diameter of the mounting holes. The coordinates/dimensions between the mounting holes. If available, a mechanical drawing (PDF or DXF) highlighting these specifications would be greatly appreciated. Thank you for your assistance. I look forward to your reply.

In this case, is t4 (controller issuing a CLR_FLT command via SPI to confirm device wake-up) mandatory in the wake-up transient of the SPI model described in section 6.7.2.2 on page 24 of the datasheet?DRV8245-Q1医疗和保健https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1094380/drv8245-q1-inventory-information/3939067Mon, 14 Sep 2026 01:40:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:d725ad08-761b-4488-ab99-e846f4c03028Vivian Gao请联系客服中心咨询非技术问题，比如库存，订单，发货等。 联系我们 | TI.com.cnhttps://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1094380/drv8245-q1-inventory-informationMon, 14 Sep 2026 01:19:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:96b51256-497e-4d78-a05c-18c7ac5f972cHenry LeePart Number: DRV8245-Q1 你好，当前官网显示该系列芯片均处于缺货状态，请问何时能正常供货，进而保证市场价格稳定？ （Hello, the official website currently shows that all chips in this series are out of stock.
