I’ve previously covered Zsun SD11x USB flash drives with 8 to 128 GB internal flash, a battery, and Wi-Fi connectivity in order to easily add storage to devices without micro SD slots. The company has now launched a new Wi-Fi card reader to do the same, but with your own micro SD card instead allowing up to 64GB extra storage, and easy replacement.
Zsun card reader specifications:
- SoC – Qualcomm Atheros AR9331 WiSoC
- System Memory – 256 Mbit RAM (32 MB)
- Storage – Internal flash for firmware (capacity TBD), micro SD slot up to 64GB
- Connectivity – 802.11 b/g/n Wi-Fi @ 150 Mbps
- USB – 1x USB 2.0 port for power and use as standard USB card reader
- Dimensions – 33 x 30 x 13 mm
There’s no battery, so you’d have to connect the dongle to a power bank, PC, car charger etc.. to power it. If you connect it to a PC it will also be shown as an external USB drive. The company claims up to 8 people can watch movies simultaneously over Wi-Fi using their Android, iOS, or Windows app, but then it must be some low resolution 3gp video… I could not find a link for these apps, but it could the same Apple Extender (Android) and Phone Flash Disk (iOS) apps as for SD111.
SD111 Wi-Fi USB flash drive is hackable, as it’s been possible to access the Linux command line with the serial console after some soldering, and later on the root password (usable with telnet) was found to be zsun1188, so the same password might also work on this device.
Zsun Wi-Fi card reader sells for 79 CNY ($12.60) in China, and $14.99 on Aliexpress. The company also sells it for $39.99 on Amazon US (Model: Zsun-C1001R) with a 64GB card inside according to the page title. Further details can be found on Zsun W-Fi card reader page (Chinese).
