Printable infographic cheat sheets for hardware and embedded engineering.

MCU Part Number Decoder→
STM32-style MCU part number decoder. Covers the suffix encoding convention (pin count, flash size, package, temperature) used by ST and 10+ Chinese MCU brands (GD32, AT32, CH32, etc.), plus gotchas where brands deviate.

AGRV2K Pin Reference→
Interactive AGRV2K (AG32VF/AG32VH) + AG10K/AG16K pin constraint reference. Two views — "By Function" (special handling, not fully capable, bonus features) and "By Chip" (one card per variant) — covering all 7 package variants, including the AG16KF256 FBGA.

Series Resistor ↔ Bandwidth→
Interactive calculator for fault-limiting series resistors on short chip-to-chip CMOS links — how big can you go before RC eats your throughput? Live microstrip solver, resistor-vs-rate-vs-fault-current table, and a simulated NRZ eye. Defaults to an AGRV2K↔AGRV2K link on 4-layer JLC 7628.

AP22653A RLIM ↔ Current Limit→
Two-way calculator for the current-limit programming resistor on the Diodes AP22652/53/52A/53A power switches (AP22653AW6-7 = LCSC C1511768). Type a resistor, get the limit; type a current, get the resistor. Min/typ/max envelope, ISHORT, nearest E96/E24 picks, and a live cross-check of the datasheet’s best-fit equations against its own spec table — they part company above 50 kΩ.
