10.1-inch RPI All-in-One PC review with Raspberry Pi 4

A couple of months ago I received “RPI All-in-One”, a 10.1-inch touchscreen display for Raspberry Pi boards, listed the specifications, checked out the package content, installed a Raspberry Pi 4 inside the display before booting my new all-in-one (AiO) PC successfully. I’ve now had time to spend more time with the PC/display and see how it performs under various conditions. I also tested HDMI and USB-C input features with a laptop and mini PC. Fan or fanless operation? After updating Raspberry Pi OS, I ran sbc-bench.sh script together with rpi-monitor to see how the Raspberry Pi 4 with 1GB RAM would perform under load with the (noisy) fan enabled.

No throttling was detected, and the temperature never exceeded 56°C in a room with an ambient temperature of 26°C. I then disconnect the fan, but it turns out the fan can also be easily disabled in the OSD menu […]

Raspberry Pi RP2040 is now available in quantities for 70 cents and up

Raspberry Pi RP2040 microcontroller has been available for one dollar in single quantities for about half a year, with at the time, 500- and 3400-pieces reel pricing to be determined. But Raspberry Pi Trading has now started to sell the chip in bulk with reels of 3,400 and 500 pieces directly to businesses for a unit price of respectively 70 and 80 cents via the new Raspberry Pi Direct website. Distributors have been selling reels for a while, but closer to 85 cents to 95 cents per unit. That basically means smaller quantities should still be purchased through distributors, but it makes more sense to purchase reels directly from Raspberry Pi Trading. Eben Upton also says they have enough wafer stock to produce 20 million chips with more on the way, so no shortage is expected. That contrasts with the current situation with many STM32 microcontrollers when some companies have […]

TinyNES – An open-source game console features original or cloned Ricoh RP2A03 & RP2C02 chips (Crowdfunding)

TinyNES open-source hardware NES game console

Tall Dog Electronics’ TinyNES (Tiny Nostalgia Evocation Square) is an open-source hardware game console compatible with NES cartridges and featuring the original MOS 6502-based Ricoh RP2A03 CPU (central processing unit) and the Ricoh RP2C02 PPU (picture processing unit) found in the Nintendo NES, although clones may be also used in the future due to the lack of availability. Designed to offer the same experience as the original Nintendo NES, the console comes with two NES controller ports, a cartridge slot, RCA video composite and mono audio outputs, and all electronics is housed in an FR-4 enclosure, the same material used for most PCBs. TinyNES specifications: CPU – MOS 6502-based Ricoh RP2A03 central processing unit, or UMC UA6527 clone PPU – Ricoh RP2C02 picture processing unit, or UMC UA6528 clone Cartridge slot for NES cartridges Controller ports – 2 original NES-style 7-pin controller ports Video – NTSC composite (CVBS) analog […]
