DSO Nano [v2] official leak
Sorry for not having this leaked earlier, because Seeed people prefer hotpot to bars…
What’s new?
1. Upgraded to semi-steel case for:
a Mechanical endurance
b Shielding of noises
c Easier assembly
2. Unibody PCB design for better reliability
3. Complete charging circuit with LTC4054 IC
4. Dedicate channel for signal generating.
5. Extra button for quick adjustment
6. Fixed battery connector
7. Compact dimension (95mm*62mm*13mm, 76g)
8. Updated software (something beyond v2.4 is on going)
Warning: This is not a brand new model but a major upgrade from previous Nano, firmwares are mostly compatible, accessories including the Contemporary Minimalism DSO Nano Stand are inherited.
Closer look:
Intro
DSO Nano v2 is a Digital Storage Oscilloscope designed for basic electronic engineering tasks. Within its smart shell, the device runs on ARM Cortex™-M3 32 bit platform, provides basic waveform monitoring with extensive functions. It equips 320*240 color LCD, micro SD card storage, portable probes, LiPo Battery, USB connection and signal generator. Due to palm size and handy performance, it fits in-field diagnosis, quick measurement, hobbyist projects and wherever convenience matters. Scheme and source files are also open for re-innovating.
