This is a set sale of two GR-SAKURA reference boards for the Renesas Electronics RX Family RX63N Group MCUs, an Xbee WiFi module S6, and an Aitendo LCD with board (2.4 inch for Sakura) LCD024GR-NP. One GR-SAKURA board has no connectors soldered. Both boards have no MMC card sockets implemented. Both boards have been stored for a long time and have not been recently tested for operation. Please understand. ★GR-SAKURA Microcontroller: RX63N (R5F563NBDDFP 100pin QFP) ROM/RAM: 1MB/128KB Data Flash: 32KB Operating Frequency: 96MHz (external oscillation 12MHz x 8) Subclock: 32.768kHz Operating Voltage: 3.3V Board Features: USB Host/Peripheral (exclusive use), Ethernet, Micro SD socket, XBee interface, JTAG interface, DC power jack (5V), user switch, reset switch, Arduino shield interface, user LED, USB mass storage-like program writing. ★LCD with Board 2.4 inch LCD024GR-NP The LCD with board was sold by Aitendo, and at the time, volunteers (such as Mr. XX Matsuura's research and development page) published programs like libraries. The CF card slot is not implemented, and power-on operation has not been confirmed. ★Xbee WiFi Xbee WiFi module S6 (PCB antenna type, the latest product seems to be S6B) This is an XBee module that supports the WiFi standard, which boasts a much higher adoption rate than the ZigBee standard. Since you can use existing wireless LAN equipment (WiFi) as is, you do not need to prepare new dedicated equipment (such as an access point) to build a wireless network. The new S6B seems to have a faster clock speed, but it also has higher power consumption, and there are reports that it has become more difficult to use. Please note that the configuration commands are not completely compatible.
