MPR121 false touches are easier to diagnose when filtered data, baseline tracking, threshold hysteresis and debounce are checked separately instead of raising every threshold.
MPR121 Ghost Touches: Read the Baseline Before Raising Thresholds Read More
Adafruit’s new 12- and 16-pixel WWA NeoPixel rings trade RGB color for individually addressable warm, cool and amber white channels in compact 5V boards.

A PN532 can acknowledge on I2C yet time out during commands when the host stack mishandles clock stretching or wake-up. Confirm interface selection, reset and request lines before switching to SPI.
PN532 I2C Timeouts: Check Clock Stretching Before Rewriting NFC Code Read More
The SHT31’s internal heater is a plausibility-check tool, not a condensation cure or normal measurement mode. Use commands 0x306D and 0x3066 with status bit 13 and label heated samples invalid.
SHT31 Heater Checks: Prove Sensor Response Without Treating Heat as Humidity Data Read More
M5Stack’s ToughC5 combines an ESP32-C5, dual-band Wi-Fi 6, Thread/Zigbee radio support, a bright touch display and 6–24V RS485 power in a field-oriented enclosure.

An SSD1306 ACK proves the controller responds on the bus, not that its panel power and scan configuration are correct. Debug a blank OLED by separating transport, initialization and framebuffer transfer.
