Key Features

• Open development platform — an experimenter's board
• Arduino / STM32duino — STM32F103C8 can be programmed over USB-C after loading stm32duino, no external programmer
• Dual-channel monitoring — INA260 current, voltage and power on two independent channels
• Load control — two P-channel MOSFETs with transient protection, switched independently
• USB comms experimentation — CDC-VCP, HID, etc
• Full hardware access — I2C bus, INA260 alert lines, load-switch pins and SWD debug header all brought out
• Flexible power — runs from USB-C or either channel input; works stand-alone without USB
• Wide ranges — 5 V to 27 V DC inputs, up to 7 A monitored per channel

Description

The KS015 gives you real power hardware to write firmware against. Each channel pairs a Texas Instruments INA260 current/voltage/power monitor on I2C with a P-channel MOSFET load switch, so a single board covers current sensing, high-side switching, and USB host communications at the same time.

Load up the STM32F103C8 with the stm32duino bootloader, then upload your Arduino IDE sketch over USB-C — nothing else to buy, nothing to configure. When you outgrow that, the SWD header (J5) takes you straight to bare-metal STM32 development with a debugger attached. The same board supports all levels of experience.

Everything is exposed rather than abstracted: the I2C1 bus (PB6/PB7) with the INA260s at 0x40 and 0x41, the alert lines on PB11/PB12, and the load-switch gates on PB0/PB1. 

Good for experimenting with: Arduino and STM32duino development on the STM32F103C8 · USB device communications, starting from a virtual COM port · high-side current, voltage and power measurement with the INA260 · P-channel MOSFET load switching and safe-operating-area limits.
