ESP8266 and ESP32 modules are widely available from numerous online retailers and electronics suppliers. Availability, pricing, and shipping times vary considerably depending on the seller and the specific module. Before purchasing, verify the module type, available flash memory, and any firmware requirements for your intended application.
Many sellers offer complete ESP development boards that include a USB programming interface and voltage regulator. These boards are often easier for beginners to use than bare ESP modules and are commonly supported by firmware such as ESPixelStick and WLED.
