I’ve been using an Onyx Boox Max Lumi 2 E-ink writing tablet for a while now, and I love it.
When I decided to buy an E-ink tablet, I researched the different products, and one of my criteria that fell into the ‘desirable’ category was whether or not the device had a MicroSD card slot.
Sadly, larger Boox writing tablets do not usually have MicroSD slots, however smaller readers do – this includes the Leaf2, Poke5, Page, and Palma.
However, the other devices do have a USB-C port that can be used to connect MicroSD cards via an OTG cable.
What is an OTG cable?
An OTG (On-The-Go) cable is a special type of USB cable that allows you to connect standard USB devices to devices with only a smaller USB-C (or MicroUSB) port. It is effectively an adapter with a male USB-C plug at one end and a female USB socket at the other.
It can connect a wide range of peripherals to phones and tablets, including keyboards, flash drives and MicroSD card expansion slots. Some flash drives even have the OTG connector built into them as a single unit.
So there you have it! Most Onyx Boox E-ink writing tablets don’t have MicroSD card slots. However, you can still expand the storage on your device by using a USB-C OTG cable to connect a MicroSD reader to the tablet. Just remember to pack the cable when you travel!
