What Sd Card Reader App Do I Want For Android

Writing an SD card, the first thing you need to do to set up a Raspberry Pi, typically involves a computer, card reader and software such Raspberry Pi Imager. But what happens when you are away from a computer and need to write a new OS for your Raspberry Pi? Well luckily there is a very useful app for Android phones and tablets.

Raspi SD Card Imager from Mike Redrobe is a tool to write operating system images for use on the Raspberry Pi. It can download and flash from a selection of images, from Raspberry Pi OS, to Ubuntu and RetroPie, all from one handy app.

If you have your own custom images, these can be written to an SD card while you are on the road. Let's take a look at this application and learn how to write the latest Raspberry Pi OS 32-bit to a microSD card for a spare Raspberry Pi 4.

What You Need

• Android device
• Adapters to connect a micro SD card reader
• Micro SD card
