Please help identify these 2.0mm pitch wafer wire to board connectors
For those that find this question later:
These are called "HY2.0 2.0mm Connectors". The 4pin version seems to also be used by Arduino Grove sensors. The HY2.0 connectors are made by many ...

Interfacing PIC18F4550 with Arduino Nano
The USART in the Arduino Nano (schematic https://www.arduino.cc/en/uploads/Main/Arduino_Nano-Rev3.2-SCH.pdf) is tied to the USB interface, which is why many projects requiring usart use bit-banging on ...

Interfacing PIC18F4550 with Arduino Nano
RX and TX can be confusing, make sure to check both datasheets to confirm the direction of each pin and make yourself a note by drawing an arrow on each and do the same for the other chip too. It ...

Please help identify these 2.0mm pitch wafer wire to board connectors
Thank you for providing clear and complete information. It allowed me to use my Connector Identification Utility that lists these possibilities:
MANUF. - SERIES
JST - PA
JST - PA + PAF
Molex - Micro-...

USART stop bit not pulled high during nRF update
The problem was the clock setting (low accuracy clock was used probably)
solution is here: https://devzone.nordicsemi.com/f/nordic-q-a/87580/issue-with-updating-nrf52832-over-usart

Data transfer FPGA To PC via UART
Sending with UART is very simple. It's a parallel to serial conversion.
Choose a pin to use for the UART signal.
When you have no data to send, output 1. When you have a data byte to send, output a 0, ...

>1Mbps UART core on Lattice's ICE40UP-5k FPGA?
The problem with UARTs > 1MHz is not the 48 MHz async clock, but the very small timing margins for FIFO flow control , and error handling with possible race conditions on the FIFO when there are ...

How to avoid noise on serial connection?
I've seen this kind of issue when you get ground noise between the boards (Jetson and motor drive). Make sure the ground current for the motor does not flow on the ground line between the jetson and ...

Unidirectional level shifter 1.8-5V -> 3.3V
I don't see why you wouldn't use a single part designed for the task such as 74LVC1T45.
(I would avoid using parts without a DIR input- the so-called automatic type).
The switching characteristics are ...

Unidirectional level shifter 1.8-5V -> 3.3V
You could do it with a two-channel comparator. Note, don't simulate with a 115 kHz square wave. Use half that frequency to get 115kbaud. A comparator in Schmitt trigger configuration with a small ...
