About the Mesp240 opll PCB
Mesp240 opll is an open source PCB design by hwreverse, published on GitHub under the MIT license. It is a 2-layer board measuring 105.7 × 129.4 mm, with 33 components from 22 distinct parts.
Other key parts include the MorphESP-240, MCP1640CH, YM2413B, LMC660 and ADG3300. By type, the board carries 13 capacitors, 8 resistors, 6 ICs, 4 inductors, 1 crystal and 1 connector.
It belongs with the dev boards & breakouts, power & battery and sensors designs in this gallery.
From the project
HWR0's Shield Designs for the MorphESP 240 by @ccadic
- Next evolution of the Gamepad Shield in a new design with two additional analog josticks and a I2C Gyroscope + Accelerometer integrated circuit for Position & Inertia capture. - 2x4 Button Gamepad Shield and connection to optional Buzzer ready to be fabricated and assembled by the PCBA service of your choice. It can also be soldered by hand as I used only 0805 and SOT-23 footprints for the passives and the transistor (on the backside). Pushbuttons are classic, comfy 12mm x 12mm x 4.3/5mm units, that won't use that much your fingertips.
