Maker Andriy Malyshenko has designed a improvement board tailor-made particularly for working with audio on an Espressif ESP32 microcontroller — and providing an elective colour touchscreen show for many who wish to throw just a little video into the combo, too.

“Loud ESP is an ESP32-powered, rich-audio improvement board. Out there with or and not using a colour touchscreen, Loud ESP has a wealth of peripherals to help a variety of consumer interplay,” Malyshenko explains. “It’s compact, moveable, battery-powered, and designed to accommodate a wide range of enclosures, all of which make it a super platform for the event of wearables and different good units.”

The board is predicated on an Espressif ESP32 microcontroller module, giving it a dual-core 32-bit Tensilica Xtensa LX6 processor operating at as much as 240MHz, 8MB of pseudo-static RAM (PSRAM), and 16MB of flash storage, together with Wi-Fi and Bluetooth radios. To this, Malyshenko has added a Maxim Built-in MAX98537 chip, giving it dual-stereo I2S audio capabilities and a built-in D-class amplifier providing 3W per channel on a four-ohm load.

Elsewhere on the board is a lithium-ion battery charging circuit for moveable initiatives, an RGB LED plus a header for an exterior RGB LED strip, and each bodily reset and flash buttons. For these opting so as to add the touchscreen, there is a 2.8″ 320×240 TFT panel plus infrared receiver, SD Card storage, JTAG debugging header, one other header for a rotary encoder or joystick, and a 14500-sized battery holder.

“Loud ESP is properly suited to various completely different functions,” its creator claims. “To call just some examples, it may be used as a conveyable speaker system with Wi-Fi and Bluetooth functionality, an internet-radio receiver, a framework for growing wearables and speaking devices, or a sensible speaker related to the platform of your alternative, resembling Spotify.”

The mission’s {hardware} design recordsdata, firmware, and utilization examples are revealed to GitHub underneath the reciprocal GNU Basic Public License 2; kits can be found to buy on Tindie for $30, or $50 with a bundled touchscreen board. These selecting up the show model, in the meantime, will discover it slots properly into enclosures designed for the Raspberry Pi 4 single-board laptop (SBC), Malyshenko says.
