ESP32-GATEWAY Rev D
About the ESP32-GATEWAY Rev D PCB
ESP32-GATEWAY Rev D is an open source ESP32 PCB design by guydmi, published on GitHub. It is a 2-layer board measuring 50.8 × 62.2 mm, with 81 components from 44 distinct parts.
Its main chip is the ESP-WROOM-32, from the ESP32 family. Other key parts include the SY8089AAAC(SOT23-5), LAN8710A-EZC(QFN32), CH340T(SSOP20W) and BAT54C(SOT23-3). By type, the board carries 31 resistors, 21 capacitors, 5 ICs, 4 inductors, 3 transistors and 2 LEDs.
It belongs with the iot & wireless designs in this gallery.
From the project
Notice that we use the latest nightly KiCad builds.
Notice that we use the latest nightly KiCad builds.
1. R54 removed. R24 and R16 moved further away from the button. 2. Improved EN signal - added C5(1uF/0603) on pin #3 of ESP32. R24 now 10k.
1. GPIO6-11, which are used by the ESP32's internal flash, were disconnected from CON1 and the 6 SD card signals are now routed instead for use when SD card is not present; 2. SD card changed from 4-bit mode of operation to 1-bit mode of operation! Added 3 NA resistor pads (R9-R11) for backwards compatiblity. 3. A lot of deep sleep mode improvements to lower the consumption to 100uA or less:
