Generating 40kHz, 60kHz, and 77. 5kHz square waves with a single MCUs . . . So, the clock offset won't meaningfully affect your receiver So, I wouldn't sweat it; if you can get a 26 041 MHz oscillator, that's going to be more than good enough However, there's also an easy way out here that only needs a much easier to get multiple: generate 40 0 kHz, 60 0 kHz, and a (77 5 - 40 0) kHz = 37 5 kHz
How to bond PCB and metal for high power RF boards Sweat Soldering is the optimum way to bond the board and the metal clad Just solder paste is required Going with adhesive will increase the cost of fabrication and also the cure temperature requirement for the adhesive will make the fabrication more complex Thank you all
High Resolution ADC for Noisy Sensors in Variable Conditions The exact ranges will change depending on how the textile is cut, whether it's soaked with sweat, the temperature, how old the material is, how it's mounted, etc The entire thing needs to be as small as possible because it's mounted on the hand, so minimizing the number of components is a big plus
Humidity design requirements - Electrical Engineering Stack Exchange Normally where people get burned is that their boards get put in a "condensing" environment even though everything is specified as "non-condensing" But that's not a design problem so much as a specifications issue tl;dr Don't sweat it and just do your design Good luck
Cable shielding (best practices) - Electrical Engineering Stack Exchange But clearly -- assuming adequate filtering is possible, it's not at all a necessary improvement, so don't sweat leaving it open, either If I am using the shield, is the above drawing optimal? Or should I do separate shielding for any signal as well? For example, [UART TX and RX in a shield] + [all remaining signals]
Electrostatic danger - Electrical Engineering Stack Exchange One potential compensating factor is that humans tend to sweat more under high temperature and humidity conditions so the effective series resistance from a human finger touch may be quite a bit lower if the finger is wet with salty sweat
power supply - Electrical Engineering Stack Exchange I’m designing a low-power wearable electronic device that will be mounted on a motorcycle helmet The device will operate mostly outdoors, and in Indian summers ambient temperatures can reach up to
