Using BTT Pad 7 touchscreen display with Raspberry Pi CM4

The BTT Pad 7, or BIGTREETECH Pad 7 in full, is a 7-inch touchscreen display that ships with the CB1 Allwinner H616 system-on-module compatible with Raspberry Pi CM4. The display is mostly designed for 3D printers with its SPI and CAN Bus interfaces, but it can also be used as a standard tablet PC. So today, I’ll switch the CB1 with a Raspberry Pi CM4 Lite module and report my experience doing the conversion and using it as a Raspberry Pi CM4 tablet PC running Raspberry Pi OS, and test it with a 3D printer with Klipper in another post later on. Installing a Raspberry Pi CM4 (Lite) module in the BTT Pad 7 We’ll need the Pad 7, a Raspberry Pi CM4, and a few tools. The first step is to remove the red heatsink by loosening four screws with a 2.0mm hex key, as well as the cover […]

Sumolink Erhu RP2040 is a $3.60 Raspberry Pi Pico clone with a USB-C port

The Sumolink Erhu RP2040 is a Raspberry Pi Pico clone with the exact same features except the micro USB port has been replaced by a USB-C port that may be preferred by some people, and the Wisdpi claims it is one of the world’s cheapest RP2040 MCU boards at $3.60, although that price does not include shipping. We had seen some other replicas, but most offer something different rather than just the USB-C port. Two examples that come to my mind are the WeAct RP2040 with a USB-C port, but also a Reset button and up to 16MB SPI flash, instead of the 2MB flash in the original board, and the Banana Pi BPI-Pico-RP2040 with an extra I2C connector and an RGB LED. Sumolink Erhu RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – 2MB QSPI flash (Note: the specs list […]
