Last December, we wrote about Up2Stream WiFi audio module designed for people wanting to build their own DIY wireless speakers. The module is based on MediaTek MT7688AN MIPS processor with 64MB DDR2 and 16MB flash storage
The module also comes with a small baseboard allowing for an easier connection to speakers. The company has now introduced Up2Stream Pro model based on the same module, but with a baseboard adding more features including Bluetooth, Ethernet, USB, and audio jacks.
Up2Stream Pro key features and specifications:
- Output – 3.5mm AUX jack and I2S header
- Input – 3.5mm AUX-in
- SNR: 91db
- THD: 0.03%
- Sample rate – 24bit up to 192kHz
- FLAC, Wav, and APE codec supported, but NOT SBC, APT-X, APT-X HD, or LDAC.
- Multiroom & Multizone support
- EQ control
- Connectivity – Ethernet, WiFi, and Bluetooth 5.0
- Protocols – Airplay, DLNA, UPnP, Spotify Connect
- Compatible Services – Spotify, Deezer, Tidal, Qobuz, Napster, iHeartRadio.
- Local Streaming from NAS or USB
- USB – 1x USB 2.0 port, 1x micro USB port
- Misc – External LED/key header
- Power supply – 5V/1A via micro USB port or 2-pin terminal block
- Dimensions – 85 x 50mm
As noted last year, this is mostly a DIY hardware convertion kit, and the company does not provide the source code for the firmware because the “multiroom streaming software is quite complicated to implement reliably”. The board can be controlled from 4STREAM app available for Android and iOS, and they also have an API to control the volume.
