Product details

The 38 general-purpose I/Os and the internal oscillator reduce external component count on a compact 108-BGA (10x10 mm) footprint.

128 KB Flash — firmware budget and OTA staging

The 128 KB Flash is sized for moderate firmware images with room for a bootloader and OTA staging buffer. The 32K x 8 SRAM supports real-time data buffering for Ethernet frames and multi-protocol stacks.

No factory orders are being accepted; the only channel is independent distribution, where stock is finite and pricing reflects scarcity.
