Part Review and Datasheet Verification

flux

Reviewed the E32-433T30D part metadata, symbol terminals, footprint outline/pads, and official datasheet sources. The Datasheet URL was already set to an official CDEBYTE endpoint, so I did not overwrite it; I also found a newer official product-page manual endpoint.
Main findings: pin count and symbol mapping match the expected 11 terminals, but pin descriptions/types are mostly missing, mechanical holes should be clearly marked non-electrical, and exact pad drill/pitch still needs mechanical drawing verification. Full review saved in part-review-e32-433t30d.

Fix the missing pin descriptions and pin types directly in the part.

flux

I’ll update each terminal with datasheet-based pin descriptions and electrical pin types, then re-read the part to confirm the properties are applied.

flux

Pin descriptions are now populated for all 11 terminals. I’m correcting VCC to the standard Power In pin type, then I’ll verify the result.

flux

Updated all 11 terminals directly in the part with datasheet-based Pin Description values and standard Pin Type values. Verified the result: M0/M1/RXD are Input, TXD/AUX are Output, VCC is Power In, GND is Ground, and the four fixed orifices are Passive.
Open items:
  • None.
Suggested next steps:
  1. Run the part review checks again.
  2. Verify footprint drill/pad dimensions against the mechanical drawing.

Pin Description
M0
1
Input
Left
Mode selection input M0; define high or low with M1 to select normal, wake-up, power-saving, or sleep/configuration mode. Do not leave floating.

Input
Left
UART receive input to module; connect to host MCU TXD, TTL serial logic.
TXD
4
Output
Left
UART transmit output from module; connect to host MCU RXD, TTL serial logic.
AUX
5
Output
Left
Auxiliary/status output from module; indicates module operating state, transmit/receive busy status, and wake/sleep timing.
VCC
6
Power In
Positive supply input for module; datasheet operating range 3.3 V to 5.2 V. Use a stable supply capable of high TX current.
GND
7
Ground
Module ground reference and power return.
