There is another version ("Mini DSO V1.00.12 // 2018-11") which differs from the images above: Comes in a pouch, ships with eight BNC to alligator cables, lacks a barrel jack, LED position has moved, rubber bumpers around case edges, no silkscreen labels on the case, signal names "engraved", teardown yet to be done. See the (updated) vendor's product page to get an idea.
Protocol
Need to continuously send commands to the OUT Endpoint, and for each command receive the result from the IN Endpoint (both Endpoints can transfer max 64 bytes). The device got logically disconnected automatically if not receive any command after 7 seconds.
List of commands (incomplete)
- A0 -> set number of channel enabled (ie. A0 02: 2 channels are enabled)
- AA -> set which channel to enable (ie. AA 01 01 00 00 00 00 00 00 enable channel 1 and 2)
- A2 -> set voltage level for each channel (ie. A2 03 03 03 03 03 03 03 03 apply +-20V range on each channel)
- A3 -> set sampling rate (ie. A3 00 set highest sampling rate)
- AC -> set sampling rate (ie. AC 07 D0 00 03 42 00 03 42 set highest sampling rate for 2 channels enabled = 1.2MS/s)
- AB -> set trigger level (ie. AB 08 00)
- C1 -> set trigger source and slope (ie. C1 00 00 for Channel 1, rising slope, C1 01 01 for Channel 2, falling slope)
- F3 -> hardware ping (required to send regularly also when acquisition is stoped, otherwise the hardware disconnect)

Buffers Reading Cycle

- A6 02 (acquire 64 bytes, 32 samples of 12 bits each, repeated 60 times get 2000 samples)
- C6 03 (return Buffer 2 size)
- A6 03 (acquire 64 bytes, 32 samples of 12 bits each, repeated 60 times get 2000 samples)
Notes
- Sample rate: maximum measured 2.4MS/s if just 1 channel is enabled. Drop down to 1.2MS/s if enable 2 channels.
- Acquisition: on each scan acquire 4000 bytes (2000 samples) from 2 buffers (2000 samples each buffer)
- Voltage Selector: the most reliable voltage selection is +/-20V, lower hardware voltages present strong non-linearity which make useless the full ADC range of the device (for example +/-500mV range is linear just in the range +500mV -> -80mV.
- Zero offset on ADC is strongly temperature dependent. It drops fast after the device is turned on (even around 50mV on a scale of +-20V). It is suggested to perform the Zero offset calibration and to use this instrument after few minutes that is on, when the temperature stabilize.
