1 December 2022Over the summer, a friend brought up a point that as an engineer, random four digit numbers bring nostalgia as part numbers. I thought I'd list a few of my nostalgic part numbers
5118 - LM5118, the buck-boost controller I used for my failed DC power supply project6398 - L6398D, the STM32 mosfet driver I tried to build an FOC controller with7224 - AT7224, the TMotor motor that we have spent two months trying to buy for UAV club4373 - MAX4373, a latching current limiter that has a depletion P channel mosfet in its application datasheet despite depletion PMOSs being practically nonexistent32U4 - Atmega 32U4, the cheap microcontroller that I used for most of my USB HID devices165, 595 - Shift register ICs that I used for button inputs and LED outputs in my flight sim projects995, 996 - MG995 and MG996 servos, which we used a ton of in UAV1604, 1624 - The two 80 cent ATTiny chips that I use religiously for small embedded projects3232 - MAX3232, the RS232 to UART bridge that we used on TJREVERB3208 - MCP3208, the 12 bit ADC that I tend to default to2209 - TMC2209, the stepper motor driver advertised on many silent 3D printer driver boards. I blew up four of these at my Starpath internship…9602N - The Iridium SBD modem that we used on TJREVERBThere are definitely more that I remember, but these are the ones that come off the top of my head
