Drive I²C without writing code.
Mission Control 3 turns bus work into point-and-click. Compose a transaction and run it, then chain a whole sequence and fire it in one go.
// point and click
Run a transaction with a click.
Compose an I²C read or write in the GUI and send it straight to your device.
// sequences
Chain them into a sequence.
Line up a series of transactions and run them together, repeatable and ready to replay whenever you need them.
// memory programming
Program EEPROM and SPI FLASH memories with ease.
Reading and writing I²C EEPROMs and SPI flash is one of the top use-cases for host adapters. Mission Control 3’s Memory Programmer does it with a visual hex editor, per-chip presets, read / write / verify / blank-check / erase, and binary file load and save, then goes places Total Phase’s Flash Center can’t.
// every os
macOS included.
Runs natively on Windows, macOS, and Linux. Flash Center is Windows and Linux only, so Mac users are stuck in a VM.

Supercharge embedded development!
// and there's more
Pulsar goes beyond two protocols.
Everything above already wins on I²C and SPI. The Aardvark stops at those two. Pulsar keeps going, so the next board that needs another bus does not cost you another tool.
// ai native
Ready for your agents.
An open, fully documented SDK lets an AI agent drive real silicon over I2C, SPI, UART, RS-485, and CAN-FD, learning the whole API from a single prompt. It is the kind of modern workflow a legacy adapter was never built for.
// the prompt
Use the Pulsar to scan the I2C bus, read the EEPROM at 0x50, and tell me what is stored there.
One sentence in. The agent learns the API, runs it on real silicon, and reports back.

Common questions.
How can I elegantly connect a Pulsar to a header designed for Aardvark?
Every Pulsar includes an adapter to enable it to directly interface with connectors designed for Aardvark's harness.
Is the Binho Pulsar a good upgrade from the Total Phase Aardvark?
Yes, and then some. The Pulsar handles the same I²C and SPI work you rely on the Aardvark for, controller and target alike, but over USB 2.0 High Speed at 480 Mbps instead of the Aardvark's USB Full Speed 12 Mbps, and at up to 6 times the SPI clock. Built-in level shifters let it talk to 1.2 to 3.3 V logic with no external level-shifting circuitry, and a programmable voltage output can power your downstream device directly. With a machined-aluminum enclosure you can mount, the Pulsar is a genuine, premium upgrade over an aging legacy device.
Does the Pulsar do I²C and SPI like the Aardvark?
Yes, as both controller and target. Pulsar is an I²C controller to 1 MHz and an SPI controller to 50 MHz, with up to four chip-selects and all four SPI modes. It also does I²C target and SPI peripheral operation, and better than the Aardvark: the target logic runs on the adapter itself, so it behaves like a real device with no host round-trip latency, at up to 16 MHz versus the Aardvark’s 4 MHz SPI slave.
What does the Pulsar add beyond I²C and SPI?
UART and RS-485, six dedicated GPIO, and a programmable 1.2 to 3.3 V DUT-power rail, plus CAN-FD and 1-Wire. One tool for the whole bench instead of a single-purpose adapter.
Does the Pulsar support MIPI I3C?
No. The Pulsar covers I²C, SPI, UART, and RS-485, but not I3C. If you need MIPI I3C, reach for the Binho Supernova: it adds I3C alongside I²C, SPI, UART, and GPIO, and runs on the very same Mission Control 3 software and SDKs as the Pulsar, so moving between them is seamless.
Explore the Binho Supernova How do I control it?
The Mission Control 3 desktop app (Windows, macOS, Linux) gives you a full GUI with no code, plus Python, Java, and C/C++/C# SDKs for automated test. Nothing to license.
Move past the Aardvark.
Same I²C and SPI, controller and target. Faster to the host, sturdier on the bench, ready for whatever your next board needs.
