# Binho Pulsar: FAQ

> Short answers to common questions about the Binho Pulsar: protocols, datasheet, calibration, several adapters at once, and the GUI.

Short answers to common questions about the Binho Pulsar.

## What protocols does the Pulsar support?

* **I2C:** controller and target, on two separate buses
* **SPI:** controller and target
* **UART:** yes
* **GPIO:** yes, 6 pins
* **RS-485:** yes, through the USB serial port
* **CAN-FD and CAN:** yes, through the USB serial port (SLCAN)
* **1-Wire:** yes, in Nova compatibility mode

I3C and Atmel Single-Wire are not supported on the Pulsar. For I3C, use the [Binho Supernova](/hardware/supernova/).

I2C and SPI target mode need firmware 4.5.0 or later, and RS-485 and CAN-FD need 4.4.0 or later. See [Firmware](/hardware/pulsar/firmware/). How each protocol works on the Pulsar: [Protocols](/hardware/pulsar/protocols/). All adapters side by side: [Protocols and Interfaces](/hardware/protocol-support/).

## Where can I find the Pulsar datasheet?

Product datasheets and other technical documents are in the document library at [my.binho.io](https://my.binho.io). Sign in to download them. The current Pulsar datasheet is revision 1.3.

## Is the ADC calibrated?

**No, on every Binho adapter.** The Pulsar has **no general-purpose analog input**. Pin 30 of its multifunction port is the 1-Wire pin. Its internal ADC reads the adapter's own voltage rails, which allows checking the target voltage. Those readings are not calibrated: use them to confirm that a rail is on, off or near its set point.

The calls, and how the reading is derived: [Is the ADC calibrated?](/support/faq/is-the-adc-calibrated/)

## Is the DAC calibrated?

**No.** The Pulsar has **no general-purpose analog output**; its DACs set the target voltage rail (VTARG), with fixed factory constants and no per-unit calibration.

The measured error of the rail: [Is the DAC calibrated?](/support/faq/is-the-dac-calibrated/)

## Can I use more than one Pulsar at the same time?

Yes. Each adapter enumerates as its own USB device (HID), and each has its own serial number. Opening a specific adapter in Mission Control 3 and in PyCosmicSDK: [Can multiple devices be used at the same time?](/support/faq/can-multiple-devices-be-used-at-the-same-time/)

## Is there a GUI for the Pulsar?

Yes. **Binho Mission Control 3** is the app for the Binho Pulsar, the Binho Supernova and the Binho Atira. It comes in two forms with the same tools: a desktop app for Windows, macOS and Linux, and a web app at [mc3.binho.io](https://mc3.binho.io/) for Chromium-based browsers. See [Mission Control 3](/software/mission-control/) and [Download & Installation](/software/mission-control/download-and-installation/).

## Can I still use the old `binhopulsar` Python package?

PyCosmicSDK replaces it and includes a compatibility layer, `pycosmicsdk.legacy.pulsarsdk`, so existing scripts run with a one-line import change. See the [migration guide](https://binhollc.github.io/pycosmicsdk/migration.html).

## What is a host adapter?
