FAQ
What are the available holes sizes?
14 mils to 150 mils - 1 mil increments
150 mils to 200 mils - 5 mil increments
above 200 mils - holes would be routed out
We only use drills in imperial units. Files submitted in metric units (mm) would be converted to imperial units (mils) and rounded up to the next mil.
I am used to designing in metric units while the website is specified in imperial units. Is there a conversion chart I can refer to ?
When requesting an online quote, the quote form can handle mm units as well as inches for dimensions.
How do I specify internal cutouts/milling in my design?
All internal cutouts/slots/milling should be specified on the same layer is the board outline. The the minimum routable slot size is 32 mils. During order time, please state this requirement in the "Special Request" section so that our CAM engineers is aware of it. This is not something we encounter often - so there are chances we may overlook it. Make sure it's known to us.

Ch375B USB Flash Drive Read Write module for Arduino , CH375 USB Device Mode
Description:
USB interface in the current electronic products accounted for a very large share of the microcontroller with USB interface communication direction of one of the most popular microcomputer application master chip module using the CH375, CH375 is a USB bus interface chip to support USB-The hOST and USB-DEVICE/SLAVE equipment the way. Locally, CH375 with 8-bit data bus and read, write, chip select control lines and interrupt output can be easily attached to the system bus of the microcontroller/DSP/MCU/MPU controller. USB host mode, CH375 also provides serial communication via serial input, serial output, and interrupt output monolithic/DSP/MCU/MPU connected.
CH375 USB device mode is fully compatible with CH372, CH375 contains all the features of the CH372. Common CH375 USB host mode support USB full-speed device, external microcontroller can through the the CH375 in accordance with the USB protocol and USB device communication. CH375 firmware also built a dedicated protocol processing Mass-Storage mass storage devices, external microcontroller can be directly used as the basic unit of reading and writing in sectors USB storage devices (including USB hard disk/USB flash drive/U disk).
