The hardware and software for a small stm32 based lab power supply

The control processor is a stm32f103c8t6, an Arm Cortex-M3 MCU with 64 Kbytes of flash memory and a 72 MHz CPU. The current code runs on libopencm3 and FreeRTOS. The display is a 256x128 OLED display. It is driven by uGui software. The unit is composed of two boards. The top board is the control and display board. The board below is the regulator board. The regulator board is composed of a low voltage drop linear regulator and a highly efficient switching regulator. Because of the combined efficiency of the switching and linear regulator not much of a heat sink is required. To reduce the…

Lps display rev 10: common questions

What microcontroller does the Lps display rev 10 use?

The Lps display rev 10 is built around the STM32F103RCT6, from the STM32 family.

How big is the Lps display rev 10 PCB?

The Lps display rev 10 measures 136.1 × 62.7 mm, has 2 copper layers and is 0.17748 mm thick.

How many components are on the Lps display rev 10?

130 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lps display rev 10 design files?

From the jerryok826/Lab-Power-Supply repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Lps display rev 10 design in my own project?
