CA-53W calculator watch

One of the open source PCB projects designed with KiCad by Gregory Davill

Overview

Gregory Davill is a technical expert from Australia who is very famous and active in the field of open source hardware. In December 2020, he insisted on designing a circuit board every day, using KiCad to complete the circuit design and PCB layout and routing. This is the adventure-calendar-of-circuits-2020 project.

This calculator watch is designed using SAML22 ARM microcontroller. This particular microcontroller has a segmented LCD controller capable of driving the LCD used inside the watch.

Using AT89C51 microcontroller to make a reversing radar
I plan to use AT89C51 microcontroller to make a graduation project of reversing radar. Does anyone have a good design plan? Software design, hardware design. I hope you can provide some information in
Please help me
Why can't I use the auxiliary clock when I use MSP430F122 for serial communication (under the default clock)? When the auxiliary clock is selected, there is no signal output on the oscilloscope from U
Short distance but reliable and stable transmission is required, Zigbee or Lora?
26 MCU nodes + 1 PC host, need bidirectional data transmission, should it be Zigbee or Lora, or other more suitable wireless networking methods? The requirements are: industrial control field, battery
Freescale MQX driver and BSP
This is a lecture from FTF2010 America, introducing the key points of Freescale MQX driver development. I upload it to share.
About the control transformer
I would like to ask about JBK5-250VA. The input is single-phase 220V, and the outputs are 220V, 220V200VA, and ~24V 50VA. I would like to ask if there is any difference between these two methods. (a)
