Sensepeek PCBite Kit Buying Guide: SQ10-Only vs SQ200 Kit vs SQ500 Kit

Sensepeek PCBite Kit Buying Guide: SQ10-Only vs SQ200 Kit vs SQ500 Kit

Sensepeek sells three PCBite kit configurations, each built around the same magnetic base plate and PCB holders but differing in the probes included. All three kits share the same DIN A4 stainless steel base plate (297 x 210 mm), four CNC-machined aluminum PCB holders, replacement test needles, insulation accessories, and a microfiber cleaning cloth. The difference is in what probes come in the box and, consequently, what measurements you can perform out of the box.

This guide breaks down the three kits so you can choose the right starting point for your team.

The Three Kit Configurations

PCBite Kit with 4x SQ10

The PCBite Kit with 4x SQ10 is the entry-level configuration. It includes four SQ10 passive 1:1 probes with 10 MHz bandwidth, plus five Dupont-to-Dupont and two banana-to-Dupont test wires. The SQ10 probes are rated for ±60 V DC / 30 V AC RMS with 200 V overvoltage protection.

Best for: Teams that primarily need hands-free probing for multimeter measurements, logic analyzer connections, or low-frequency signal observation. If your workflow involves decoding SPI, I2C, UART, CAN, or JTAG using a logic analyzer, the SQ10 kit gives you four stable probe points with the full PCBite mechanical platform. It is also the right choice if you already own oscilloscope probes and only need the base plate and holders for board fixturing.

PCBite Kit with 2x SQ200 + 4x SQ10

The PCBite Kit with 2x SQ200 + 4x SQ10 adds two 200 MHz passive 10:1 oscilloscope probes to the four SQ10 probes. The SQ200 probes feature 10 M-ohm input impedance, 13.9 pF input capacitance, and 300V RMS CAT II voltage rating. They support automatic 10:1 probe detection on compatible oscilloscopes.

Best for: The broadest range of embedded hardware debugging. At 200 MHz bandwidth, the SQ200 probes cover SPI clock validation up to 40 MHz, I2C fast-mode, PWM waveforms, UART signals, CAN bus analysis, and power supply ripple measurements. The 300V CAT II rating makes them safe for offline converter work. This is the most popular kit configuration for R&D labs in Bengaluru, Hyderabad, and Pune doing general-purpose embedded development. The four SQ10 probes handle your logic analyzer and multimeter connections while the two SQ200 probes cover oscilloscope channels.

PCBite Kit with 2x SQ500 + 4x SQ10

The PCBite Kit with 2x SQ500 + 4x SQ10 is the premium configuration, pairing two 500 MHz passive 10:1 oscilloscope probes with the four SQ10 probes. The SQ500 probes deliver the same 10 M-ohm impedance and 300V CAT II rating as the SQ200, but extend bandwidth to 500 MHz and reduce input capacitance to just 9 pF.

Best for: Teams working with USB 2.0 (480 Mbps), LVDS, MIPI CSI/DSI, DDR memory interfaces, or fast-switching GaN/SiC power devices. The lower 9 pF capacitance also matters when probing high-impedance nodes where the SQ200’s 13.9 pF would introduce visible signal loading. Hardware design centers in Chennai and Mumbai working on consumer electronics, high-speed digital boards, or advanced power conversion benefit from the extra bandwidth headroom.

The Modular Upgrade Path

A key advantage of the PCBite platform is that every probe uses the same magnetic mount and 0.5 mm exchangeable needle. You can start with the SQ10-only kit and add individual SQ200 or SQ500 probes later. You can also extend any SQ-series kit with SQG high-frequency probes (1.5 GHz to 6 GHz) when signal integrity work enters your scope.

This modularity means the initial kit decision is not permanent. However, buying the right kit upfront avoids the incremental cost of purchasing probes individually. The SQ200 and SQ500 kits include their oscilloscope probes at a lower effective price than buying the SQ10 kit plus individual oscilloscope probes separately.

Decision Framework

If you are setting up a new lab bench or equipping a team, the decision comes down to one question: what is the highest frequency content in the signals you measure most often?

• Below 10 MHz (DC rails, low-speed buses, logic levels), Start with the SQ10 kit
• Below 40 MHz fundamental (SPI, I2C, UART, CAN, PWM, power supplies), The SQ200 kit covers your needs
• Above 40 MHz fundamental (USB 2.0, LVDS, MIPI, DDR, fast switching), Invest in the SQ500 kit

When in doubt, the SQ200 kit is the safe middle ground. It handles the vast majority of embedded debugging scenarios, and you can always add SQ500 probes individually for the occasional high-speed measurement.
