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...
USBasp - USB ISP/TPI programmer for Atmel AVR microcontrollers based on the design by Thomas Fischl.
This is the MT3608 with a micro USB. It is a exact copy of the famus MT3608 board.
It is a DC-DC step up adjustable boost converter. It can take input voltages as low as 2V and step up the output to as high as 28V. You can supply electricity via micro USB. The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. It includes under-voltage lockout, current limiting,...

This is a work in progress, and I am only a hobbyist!
This is a 3.3V max. 1A power supply for microcontroller circuits, based on a [Texas Instruments Webench Power Designer](https://webench.ti.com/power-designer/) [design report](https://easyeda.com/attachments/2020/2/VcRQzQEVQVHQ84x7PkTshqI471yGhASCPhwpucvl.pdf) using a [TPS82084SIL](https://www.ti.com/product/TPS82084) step-down converter with...
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...
