Bluepill-serial-monster is a STM32 Blue Pill board that turns it into triple USB-to-Serial adapters.
The board implements a USB 2.0 full-speed composite device that consists of 3 USB CDC devices.
STM32 Blue Pill is a ridiculously cheap STM32 development board which is available in many stores around the globe. The board contains decent hardware that supports USB 2.0 Full-Speed, has 3 independent...
This board utilize an ATTINY85 chip to control a servo motor using Serial Command, featuring a MOSFET for switching on/off the servo motor, an AMS1117 3.3 regulator to provide power for the ATTINY85chip and a status LED. Program not included. You have to use Software Serial on Port 3 and 4.
Recommend Serial Command: M-Command
My version of arduino with ARK connectors and better voltage regulators.
Fully working board
This version of board allow you to upload your code via usb uning CH330N microchip
Now there is also 3.3V high current voltage regulator as well as 5V
This is a tiny (Bare PCB dimension: 45mm(W) x 20mm(H)) USB to serial converter using the low cost CH340c chip with a few surrounding parts. The advanctage of CH340c is no external crystal needed that could cut down the cost. The mainly used pin at the tail of the board is compatible with FTDI breakout board, so you can use it to program Arduino Pro mini by temporary touching the pins of the boards...
# ESP 32 input output board/ shield #
8 opto-isolated inputs
8 10 amp relay outputs
Serial, 1 Wire comunication ports.
Just plug in a ESP32test module and programm it.
Used it with Jeedom and the Jeeduino plugin.
USB RS232 Relay
The main objective of this board is to ring an school bell using a PC program written in python.
- This project is the interface of a PC to a Relay using a simple USB RS232 adapter.
- This approach was selected because the parts are easily found in any PC parts store.
- The relay is activated/deactivated using the RTS line of the serial port, any...
RS-232 DE-9 Break-out Board
Allows for special wiring of RS-232 connections.
Jack 1 Pins 1,2,3,4,6,7,8,9 can be connected to Jack 2 Pins 1,2,3,4,6,7,8,9 in any combination.
Allows for easy handshaking and DTE/DCE adaptation.
Use Bi-directional, dual color LEDs for signal status indicators.
"The Missing Module"
Pairing this module with S. Cousins SC108 (CPU+memory) or SC114 SBC form a complete CP/M computer system.
The beauty with #61 is that it can be used as a
1) bus clock
2) serial interface
4) or a combination of these functions.
In addition, it allows the CPU to run asynchronously up to 24Mhz (Z80) or 33Mhz (Z180)
