<br />
The Original ESP32 family was introduced by Espressif Systems in 2016 as the successor to the ESP8266. It combines Wi-Fi, Bluetooth, significantly greater processing power, additional GPIO, and expanded peripheral support into a single, low-cost microcontroller.<br />
<br />
The Original ESP32 remains one of the most popular processor families for DIY holiday lighting because of its excellent balance of performance, flexibility, community support, and low cost.<br />

<br />
== Overview ==<br />
<br />
The Original ESP32 family is based on Espressif's Xtensa LX6 processor architecture and is available in both single-core and dual-core versions. Most development boards used in Christmas lighting applications utilize the dual-core versions.<br />
<br />
Typical features include:<br />
<br />
* 2.4 GHz Wi-Fi (802.11 b/g/n)<br />
* Bluetooth Classic<br />
* Bluetooth Low Energy (BLE)<br />
* Up to 240 MHz CPU<br />
* Up to 34 usable GPIO<br />
* Hardware PWM<br />
* SPI<br />
* I²C<br />
* I²S<br />
* UART<br />
* ADC<br />
* DAC (selected devices)<br />
* Capacitive touch inputs (selected devices)<br />
<br />
== Common Modules ==<br />
<br />
Several ESP32 modules have been produced by Espressif. While they share the same processor family, memory size, flash capacity, PSRAM, antennas, and certifications may vary.<br />
<br />
Common modules include:<br />
<br />

! Description<br />
|-<br />
| ESP32-D0WD<br />
| Original dual-core processor used in many modules.<br />
|-<br />
| ESP32-WROOM-32<br />
| Most common general-purpose module.<br />
|-<br />
| ESP32-WROVER<br />
| Adds PSRAM for applications requiring additional memory.<br />
|-<br />
| ESP32-SOLO-1<br />
| Single-core version of the ESP32.<br />

<br />
== Typical Development Boards ==<br />
<br />
The Original ESP32 processor is found on many development boards, including:<br />
<br />
* ESP32 DevKit<br />
* NodeMCU-32S<br />
* LOLIN32<br />
* DOIT ESP32 DevKit<br />
* ESP32 DevKit V1<br />
<br />
Although these boards often appear similar, GPIO assignments, USB interfaces, regulators, and pin layouts may differ.<br />
<br />
See [[ESP32 Development Boards]] for additional information.<br />
<br />
== Christmas Lighting Applications ==<br />
<br />
The Original ESP32 is well suited for:<br />
<br />
* WLED controllers<br />
* ESPixelStick controllers<br />
* Multi-output pixel controllers<br />
* DDP and E1.31 networking<br />
* Matrix displays<br />
* Large pixel props<br />
* Ethernet-based controllers (using external hardware)<br />
<br />
Its combination of processing power and abundant GPIO makes it one of the most versatile controllers available for DIY holiday lighting.<br />
<br />
== Advantages ==<br />
<br />
* Excellent community support<br />
* Widely available<br />
* Low cost<br />
* Dual-core performance<br />
* Large number of GPIO<br />
* Extensive firmware support<br />
* Mature software ecosystem<br />
<br />
== Limitations ==<br />
<br />
Compared to newer ESP32 families:<br />
<br />
* No native USB<br />
* Higher power consumption<br />
* Older Xtensa architecture<br />
* Fewer security features than newer devices<br />
<br />
Despite these limitations, the Original ESP32 continues to be one of the best all-around choices for Christmas lighting applications.<br />
