taorye 775a2e6c5b docs(slogic32u3): point new users to the firmware update tool

Units may ship with firmware older than the latest release. Add a short
tip to the Quick Start unboxing section that links the firmware downloads,
the online update tool and the full steps, and list the update tool under
the Introduction's links.

Introduction

Overview

The SLogic32U3 is the flagship logic analyzer of the Sipeed SLogic series, and the world's first logic analyzer with a USB3.2 Gen2 interface. In a 59×51×13 mm CNC aluminum enclosure it delivers 32-channel high-speed Stream capture: 1400M@4CH, 800M@8CH, 400M@16CH, 200M@32CH, with a digital signal bandwidth up to 350 MHz.

Backed by the USB3.2 Gen2 interface and an onboard 2 Gbit DDR3 elastic buffer, it sustains 800 MB/s (6.4 Gbps) in practice, streaming waveforms straight into your PC's memory or even disk, no longer bound by device-side buffer depth. Digital inputs accept a 0–10 V range with a 0–6 V adjustable threshold, and an optional 4-channel ADC module gives the same device sampling-oscilloscope capability.

On the host side, Sipeed officially provides SLogicView, ngscopeclient and sigrok-cli, plus the install-free web app SLogicWeb (slogic.sipeed.com) — you can capture right in a browser, even on an Android phone.

🎉 The SLogic32U3 is crowdfunding now! Back us on Kickstarter.

Features and Specifications

Key features

USB3.2 Gen2 high-speed interface: The world's first USB3.2 Gen2 logic analyzer. Interface line rate 10 Gbps, and with the onboard 2 Gbit DDR3 elastic buffer it sustains 800 MB/s (6.4 Gbps) in practice, keeping high sample rates even at high channel counts.
32 channels / up to 1400 MSa/s: 1400M@4CH, 800M@8CH, 400M@16CH, 200M@32CH, covering everything from single-bus debugging to multi-lane parallel bus analysis.
350 MHz digital signal bandwidth: Enough for SD UHS-I, eMMC HS200, Octal-SPI and other high-speed buses.
Adjustable threshold + wide input range: 0–10 V digital input, 0–6 V adjustable logic threshold (0.1 V steps), matching 1.2V / 1.8V / 2.5V / 3.3V / 5V and other logic levels.
Mini-HDMI coaxial shielded probes: The 32 channels are split into 4 groups of 8, each group merged into one Mini-HDMI connector; the 15 cm coaxial shielded cable markedly improves high-speed signal integrity over plain jumper wires.
Optional ADC → oscilloscope: An optional 4-channel ADC module (8-bit, 100 MSa/s, 10 MHz analog bandwidth, ±15 V safe input) turns the same device into a sampling oscilloscope for mixed-signal observation.
Multiple host apps + install-free web app: Choose SLogicView (default), ngscopeclient or sigrok-cli as needed; the web app SLogicWeb needs no install and runs on Android too.
Easy OTA: Firmware can be updated online.
