ESP32-based dual-port WLED controller features Ethernet port, 24V DC input

When it comes to ESP32-based WLED controllers, some of the best options are boards like the Adafruit Sparkle Motion, Mini Sparkle Motion, and Sparkle Motion Stick, but most of the time, they are out of stock. Thankfully, there are similar alternatives like the xChroma WLED Type-C and HACK Lab HackLED Pro, with similar features and wider availability. Now adding to that list is the 2-Port ESP32 ETH0 WLED Controller, which not only adds Ethernet connectivity but also supports dual outputs and 5V–24V LEDs, making it an excellent alternative to the Adafruit ones. The board supports both Ethernet and Wi-Fi connectivity and includes an onboard DC-DC converter that delivers a stable 5V supply to the ESP32 and logic circuits. Each output channel is fused with a 6A resettable polyfuse and a status LED that lights up during fault conditions. For added safety, the main power input is protected against reverse polarity, […]

Raspberry Pi CM0 castellated module features Raspberry Pi RP3A0 System-in-Package

Raspberry Pi CM0 is a yet-to-be-officially-announced castellated Compute Module based on the Raspberry Pi RP3A0 SiP (System-in-Package) found in the Raspberry Pi Zero 2 W and Raspberry Pi Compute Module 3E (CM3E). Since most Raspberry Pi products are announced under a strict embargo, I’m always surprised when I find new Raspberry Pi hardware that was never formally introduced. But it seems to happen from time to time for products targeting business customers specifically. The CM3E Compute Module was one example, and the CM0 appears to be another. Raspberry Pi CM0 specifications: SiP – Raspberry Pi RP3A0 SoC – Broadcom BCM2710A1 CPU – Quad-core Cortex-A53 processor @ 1.0 GHz GPU – VideoCore IV GPU supporting OpenGL ES 1.1, 2.0 graphics VPU – H.264/MPEG-4 1080p30 video decoding, H.264 1080p30 video encoding System Memory – 512MB LPDDR2 RAM Storage – 0GB (Raspberry Pi CM0 Lite), 8GB, or 16GB eMMC flash Wireless – Optional […]
